Photoshop Masking and Compositing: Advanced Blending

Photoshop Masking and Compositing: Advanced Blending

with Deke McClelland

 


Advanced Blending is the second installment in Deke McClelland's series on making photorealistic compositions in Photoshop. The course explores blending options and shows how to use them to create sophisticated effects and seamless compositions, often without masking. Beginning with the basics of blending layered images, the course sheds light on the formulas behind the Photoshop blend modes and shows how to comp scanned line art, create double-exposure effects, correct skin tones, and work with the luminance sliders.
Topics include:
  • Assembling dynamic Dissolve effects
  • Filling and stroking with Behind and Clear
  • Cleaning up and compositing scanned line art
  • Understanding the darken, lighten, and contrast modes
  • Refining a mask with Multiply and Screen
  • Creating a glowing, soft-focus effect
  • Blending images with textures
  • Comparing two seemingly identical images
  • Creating type that inverts everything behind it
  • Colorizing artwork with layers
  • Achieving greater control with the Blend If option

Introduction
Welcome
00:04Hi! I'm Deke McClelland.
00:05Welcome to Photoshop Masking & Compositing: Advanced Blending.
00:11My detailed guide to understanding and employing the Byzantine, but extremely
00:16useful network of blending options in Photoshop.
00:20I'll start by introducing you to the core concepts.
00:24What blending is, how the most important options work, as well as all the shortcuts.
00:30Then we move into the specific blend modes.
00:33I show you not only uses for each of the blend modes of which there are many,
00:38but I also try to give you a sense for how the modes work and what purpose they serve.
00:43There's no end of possible compositing scenarios and I want you to have a clear
00:48sense for what you can accomplish and how so that you're never left frustrated
00:53or scratching your head.
00:55I wrap things up by showing you how to use the Luminance Exclusion slider bars
01:00as well as the Blend If option, all of which allow you to drop out or force
01:05through specific luminance levels without masking a single pixel.
01:11Now a word of warning upfront, Chapter 2 is all about the math.
01:16For those of you who like and understand basic formulas, you'll find this
01:21immeasurably useful.
01:23But if you don't like math, no problem, just skip Chapter 2 entirely, don't
01:29watch a single movie.
01:30You won't miss a thing, I promise you.
01:33And with that I turn you over to what I hope to be the most comprehensive
01:38discussion of blending ever assembled.

1. The Power of Blending
When in doubt, blend
00:00The most common use for blending is to avoid masking altogether, which means
00:05that you can get your work done more quickly, you can oftentimes achieve better
00:08results, and you can do so entirely nondestructively.
00:13For example, let's say we want to take this tic-tac-toe doodle and we want to
00:16express it in white against a different background.
00:18Now you might figure the best approach, and it's actually a pretty simple one,
00:23is to switch over to the Magic Wand Tool and then go up to the Options Bar
00:27assuming default settings, you would turn off the Contiguous checkbox, then
00:31click anywhere inside of a black region which will select all the black
00:35throughout the graphic.
00:36Turn off that doodle layer because we don't need it now.
00:39Create a new layer by pressing Ctrl+Shift +N or Command+Shift+N on the Mac, let's
00:43go ahead and call this layer white.
00:45And then assuming that white is your background color, press Ctrl+Backspace or
00:49Command+Delete on the Mac in order to fill that selection with white.
00:52And that's all there is to it, right.
00:54So I'll go ahead and press Ctrl+D or Command+D on the Mac in order to
00:57deselect the image.
00:58But I'm going to zoom in here to 200%, switch over to the other image so that we
01:03can compare it, zoom in as well.
01:05Now let's go ahead and scroll these images.
01:08I want you to see this region right there.
01:10Notice the detail that we have.
01:12It looks great inside the final version of the composition.
01:16And inside the version we've created so far, it looks pretty darn choppy.
01:19Thanks to the limitations of working with the Magic Wand.
01:22Here's the better approach, one that doesn't require masking at all,
01:26it's entirely blending.
01:28I'll go ahead and zoom out from the image once again, turn off that new white
01:31layer I just created, turn on the doodle layer, click on it to make it active,
01:35and then press Ctrl+I or Command+I on the Mac in order to invert it.
01:40Now all we need to do is drop out the blacks and keep the whites using a Blend Mode.
01:45And the Blend Mode that we would use in this case is Screen.
01:49So I'll go ahead and choose Screen from the Blend Mode pop-up menu and we end up
01:53achieving this result here;
01:54entirely nondestructively as I say because I haven't had to modify a single
01:59pixel inside the original layer.
02:01Now you might say, well, you did have to invert it.
02:03But as you may recall, inverting is entirely a nondestructive operation
02:08because I can re-invert that layer anytime I like it in order to return back to the original.
02:13And that simply put is the power of blending as a compositing tool here inside Photoshop.

Where to find blending options
00:00In this exercise, I'll give you a sense of where you can find the blending
00:03options inside Photoshop.
00:04Specifically I'm talking about the Opacity value and at least 27 out of a
00:09potential 31 blend modes that are offered by the program.
00:13Now the blending options are fairly ubiquitous.
00:15We'll just be seeing a few examples.
00:17Specifically, I'll show you how to blend using the Gradient Tool.
00:20This is a destructive modification which means you will rewrite the pixels
00:24in the active layer.
00:25We'll also blend with the Brush Tool, another destructive modification.
00:30And finally, we'll blend from the Layers Panel which is
00:33altogether nondestructive.
00:35But this is just the tip of the iceberg.
00:37You'll also find blending options when working with other tools, specifically
00:41the Clone Stamp Tool and the History Brush, but you'll find subsets of the
00:45blending options when working with the Healing Brush, the Smudge Tool, and many others.
00:50We've got the Fill and Stroke commands which are both available under the Edit menu.
00:54These options that we're seeing so far down here in the bottom right corner of
00:58the screen, these are destructive modifications.
01:00However, if you blend using layer effects, that's absolutely nondestructive.
01:05And then we've got the Calculations and Apply Image commands both available
01:08under the Image menu.
01:10We'll see a lot of them when we're creating complex masks in other courses in this series.
01:14And frankly, these are just the features that I can remember off the top of my
01:18head, there are probably many more.
01:21So let's get started here.
01:22I'm going to go ahead and hide those overlays.
01:24Notice that I have the spheres layer selected here inside the Layers Panel.
01:28I don't want to affect this red ball in the center here, I just want to
01:31affect the white ones.
01:33So I've already got this Layer Mask that I've created in advance.
01:36I'm going to Ctrl+Click on it or Command +Click on that Layer Mask thumbnail in
01:40order to load the selection.
01:41Then I'll go up to the Select menu and choose the Inverse command so that I've
01:45selected the white balls in the background.
01:48Now I'm going to switch to the Gradient Tool which you can get by pressing the
01:50G key and I'm going to switch my Gradient to this guy right here, one that I
01:55never use, I have to admit, Red, Green, but it's very handy, up here in the Options Bar.
02:00Otherwise my settings are set to their defaults, I'll be creating a Linear
02:04Gradient, the Reverse checkbox is turned off, the others are turned on.
02:08Here are our blending options by the way.
02:11I could modify my Opacity value if I wanted to.
02:13However, what I'm going to do is change the Blend Mode from Normal to this
02:18guy down here, Color.
02:19We'll be discussing how every one of these blend modes works by the way.
02:24Right now I'm just showing you one possible application.
02:26And I'm going to drag from the bottom of the image up to the top, like so, while
02:29pressing the Shift key to create a vertical gradient as you see here.
02:33Alright, now let's switch over to the Brush Tool.
02:36I'll go ahead and click on it or I could press the B key.
02:38And then I'm going to right-click inside of the Image Window to bring up the Brush Panel.
02:43Notice that I've expanded it a little bit.
02:45So I can get to this custom brush, Scattered Maple Leaves.
02:48And now I'm going to increase my Size value to 200 pixels and press the Enter
02:52key couple of times, the Return key a couple times on the Mac in order to
02:55accept that change.
02:56Let's go ahead and dial-in a shade of green, I'm going to change my Hue value to
03:0090 degrees, my Saturation to a 100, and my Brightness value to 50%.
03:05And now notice if I were to just start painting inside the Image Window, I would
03:09paint a series of Opaque Leaves.
03:10That's not what I'm looking for, so I'll press Ctrl+Z, Command+Z on the Mac.
03:15When you're working with any of the painting or editing tools, you can
03:18change your blending options from the Options Bar just as you can with the Gradient Tool.
03:22I'm going to switch my Mode from Normal to Multiply so that I'm burning in the
03:26leaves and then I'll go ahead and paint them in.
03:28Once again, notice that I get this interaction between the leaves and the
03:32bulbs in the background.
03:34Finally, I'm going to go ahead and turn on this texture layer right there.
03:37Notice that this marble texture exists entirely inside the red ball.
03:41Press the M key to switch back to my Rectangular Marquee Tool and press Ctrl+D
03:45or Command+D on the Mac to deselect the image.
03:48And now let's go ahead and merge that texture into the spheres layer below by
03:53clicking on the texture layer to make it active, and then switching the Blend
03:57Mode in this case from Normal to Linear Burn which gives us this nice darkening effect.
04:03And those, friends, are just a few of the places that you can apply blending
04:06options here inside Photoshop.

27 blend modes, 6 groups
00:00In this exercise, I'll introduce you to the 27 common blend modes that are
00:04found inside Photoshop.
00:05These are the modes that you see when applying layer effects, when working with
00:09the Brush Tool, the Gradient Tool, and so forth, when applying the Fill
00:12command, the Stroke command, and most commonly, when working inside the Layers
00:16panel, which is why I'll be framing my discussion for now in terms of working with layers.
00:21And as you may know, every single one of the blend modes produces a unique
00:25effect, a unique interaction between different layers, for example.
00:29But it's rarely evident what those interactions are going to be.
00:32For example, what does the Overlay mode do, what does Soft Light even mean, and so forth?
00:38Well, we'll be discussing each and every mode in more detail in a future
00:41chapter, but for now, I want you to notice how the modes are actually combined
00:46into six different groups.
00:48And that tells you that each of the modes inside the groups is related to each other.
00:52So let's take a look at how those groups work.
00:55I have opened an image called The 27 blend modes.psd found inside the 01_intro folder.
01:01Let's start off by taking a look at the Normal modes which include Normal and Dissolve.
01:05Now Normal, strictly speaking, is not a blend mode.
01:08In fact, it turns the blend mode off so that we're creating an interaction
01:12between layers, for example, exclusively using the Opacity values.
01:17Dissolve is a lot like the Normal mode.
01:20It doesn't create any specific interaction between pixels.
01:23Instead, it goes ahead and applies a dither pattern to the translucent areas, so
01:28you get noise around the edges of the soft image, for example, and we'll see
01:32what that looks like in the very next chapter.
01:34Next we have the Darken modes and when you chose a Darken mode, you use the
01:38active layer to darken the layers below it as if that layer is casting a shadow.
01:43Now I'll be devoting an entire chapter to this group of modes.
01:47But in the meantime, it's often useful to think of these modes as burning
01:51colors in, just as when you burn a piece of toast, for example, you end up darkening it.
01:57Next we have the Lighten modes which use the active layer to brighten the layers
02:00below as if creating a glow.
02:02Each of these modes has an opposing mode as paired sequentially in a Darken group.
02:07So what I mean by that, for example, is that the Lighten mode is effectively the
02:11opposite of the Darken mode, whereas Screen is effectively the opposite of
02:16Multiply, Color Dodge is the opposite of Color Burn, and so on down the list.
02:22The next group is the largest one.
02:24We've got seven Contrast modes in all, all the way from Overlay down to Hard Mix.
02:29And in the case of these modes, the dark pixels in the active layers burn in the
02:33shadows, so they darken those shadows.
02:36The light pixels boost the highlights.
02:38So in other words, we're darkening the darkest pixels, lightening the lightest
02:41pixels, and the result is an elevation in the contrast of the composite image.
02:46Once again, I'll be devoting an entire chapter to this group of modes.
02:50The next group is a little bit of a muddle.
02:52It's kind of a two groups in one.
02:54First we have the Difference and Exclusion modes, which are the so-called
02:58Inversion modes because they use the active layer to invert those below.
03:02Similar pixels, that is, a pixel in the active layer that's very similar to the
03:07pixel directly below it becomes black in the case of the Difference mode or gray
03:12in the case of the Exclusion mode.
03:15Subtract and Divide are the Cancellation modes and they cancel pixels by
03:19clipping them to black in the case of the Subtract mode, or white in the case
03:23of the Divide mode.
03:25These guys are a little unusual, a little bit complicated as well.
03:28They can be pretty useful, however, and once again, I'll show you how they work
03:32in a future chapter.
03:34Finally, we have the Component or so-called HSL modes.
03:37A pixel that is the color of the pixel, can be expressed as a combination of the
03:42primary component's Hue, Saturation, and Luminosity.
03:46Now Color is a combination of Hue and Saturation mixed together.
03:51And I mentioned that because if you look at the modes, we have Hue and
03:54Saturation and then Luminosity down here at the bottom.
03:57Color, as I say, is a combination of the two above it.
04:01These final modes, that is, Hue all the way down through Luminosity mix the
04:05primaries independently in order to achieve different effects.
04:09So I know that's an awful lot of information to take in, in one movie.
04:12But for now here's where I want you to remember.
04:15We've got 27 common blend modes in all organized into a total of six groups
04:20here inside Photoshop.

Opacity vs. Fill Opacity
00:00In this exercise, I'll explain the difference between the two numerical blending
00:04options here inside the Layers panel, the first of which goes by the name
00:07Opacity and the second of which is called Fill, short for Fill Opacity.
00:12I'm working inside a file called Sample type.psd found inside the 01_intro folder.
00:17And notice that we have two identical words set in the font Myriad Pro, both of
00:21which are located on independent layers.
00:23I'm going to start things off by making the top layer active, then I'll click on
00:27the word Opacity in order to highlight its value there in the Layers panel, and
00:31I'll change the value to 25%.
00:34Then I'll click on Sample #2 in order to make it active, click on the Fill this
00:38time in order to make its value active, and change it to 25%.
00:43And you'll notice that both effects are absolutely identical to each other.
00:48And that thrills a lot of people because after all, why have two values that
00:52serve exactly the same purpose.
00:54Well, the problem with the demonstration so far is that all we have to work with
00:59is Fill that is the pixels inside of the layer.
01:02And both Opacity and Fill affect those pixels at least where the Normal and most
01:07of the other blend modes are concerned in exactly the same way.
01:10Where they start to become different than each other is when we have layer effects.
01:15So I'm going to go up to the File menu and choose the Revert command or press
01:19the F12 key in order to restore the original version of the image.
01:23Notice that both of these layers have layer effects associated with them.
01:26I'll go ahead and turn those layer effects on like so and then I'll select the
01:30top text layer, click on Opacity, and once again change that value to 25%, and
01:36notice that the interior of the type as well as the layer effects fade in kind.
01:41Compare that to what happens when I select the second text layer, click on its
01:45Fill value and change it to 25%.
01:48And notice this time we reduced the Opacity of the letters that is the white
01:52inside of the letters, but the layer effects remain as opaque as they ever were.
01:57And where this becomes really useful is when you take that Fill value and reduce
02:01it all the way down to 0% which is when you have layer effect and nothing more.
02:06So the letters themselves entirely disappear and as a result, they appear to be
02:11embossed into that background.
02:13Now a few things you should know about modifying these values.
02:16If I click on the top text layer, as we've seen, you can change the value by
02:20clicking on it and then entering another value.
02:22You can also click on this right- pointing arrowhead to bring up a little slider
02:26bar like so, or if you want to, you can scrub directly on the value in order to
02:31change it on the fly.
02:33If you want to change the value in larger increments, specifically increments of
02:3610, then you press the Shift key while scrubbing on that value and each pixels
02:41worth of scrub at this point will result in a 10% variation.
02:46And then, finally assuming that any tool in the toolbox except for this second
02:51group of tools right here, the Paint and Edit Tools, anything else including the
02:55Selection Tools or the Pen Tool all the way down to the Zoom Tool in the latter
02:59half of the toolbox, when any of those tools is selected, you can just press a
03:03number key on the keyboard.
03:05So for example, if you press the 1 key, you'll reduce the Opacity to 10%.
03:10If you press 2, you'll get 20%, 3 for 30%, all the way up to 0 for 100%.
03:15If you press two keys in order such as 4, 5, then you'll end up changing the
03:21value to in this case 45% and so forth.
03:25The lowest you can go there for is 0, 1 for 1% opacity.
03:30If you want 0% opacity, you're going to have to either scrub it down or enter
03:35that value and so on. All right!
03:36I'm going to press the 0 key in order to restore an Opacity value of 100%.
03:40The same goes for the Fill value incidentally.
03:44So if I click on that second type layer, then I can go ahead and for example,
03:49scrub that value upward or I could press the Shift key and scrub it all the way up to 100%.
03:55If you want to change the value on the fly when any tool but that second group
03:59of tools is selected, then you press Shift along with a number key.
04:03So for example, Shift+1 changes the Fill value to 10%, Shift+2 for 20%, Shift+3
04:09for 30%, all the way up to Shift+0 for 100%.
04:13And if you have the Shift key down while typing two numbers in a row, for
04:16example, I'll type Shift+6+7.
04:19Then I'll change that Fill value to 67%.
04:22Therefore, once again the lowest you can go is Shift+0+1 for a Fill value of 1%.
04:27If you want to go lower than that all the way down to 0%, for example, then you
04:31have to scrub that value all the way down.
04:34And that's how you work with the Opacity and Fill values here inside
04:38Photoshop's Layers panel.

The "Fill Opacity Eight"
00:00Now the primary purpose of the Fill value is exactly what I showed you in the
00:03previous exercise that is it allows you to modify the opacity of the layer
00:08itself independently of layer effects and other specialized layer functions.
00:13However, out of the 27 common blend modes, eight of them are affected
00:17differently by the Fill value than they are by the Opacity value and frankly,
00:22between you and me, they are better affected by fill and I call these the
00:26Fill Opacity Eight.
00:28Now I haven't demonstrated how these modes work yet, however, when we get to our
00:31specific blend mode discussions in subsequent chapters, it will be important
00:35that you're familiar with this information.
00:38So, the Fill Opacity Eight include inside the Darken group, both Color Burn and Linear Burn.
00:44Inside the Lighten group, we have Color Dodge and Linear Dodge (Add) that's
00:49actually the name of the blend mode.
00:51In the Contrast group, we've got three of them;
00:54we've got Vivid Light, Linear Light and Hard Mix and then finally, in the
00:58Inversion group, we have the Difference mode.
01:00So just so that you have a sense of what's going on here, I'll demonstrate a
01:04few of these modes.
01:05I am working inside a document called Fill Opacity Eight.psd found inside
01:09the 01_intro folder.
01:10I am going to go ahead and turn off the top three layers.
01:13Notice that that the Assyrian layer is selected inside the Layers panel.
01:17Then I'll go up to the Image menu and create a copy of the image by choosing
01:20the Duplicate command and I'll call this duplicated image Standard Opacity and click OK.
01:25All right!
01:26Now I want to display the two images side-by-side.
01:29So with this new image selected, I'll go up to the Arrange Documents icon, up
01:34here in the Applications bar, click on it and choose the vertical 2 Up option.
01:38And because the Standard Opacity window was active, it now appears on
01:42the left-hand side. All right!
01:44I'll now press Shift along with the Spacebar so I can scroll both of the images
01:48at the same time like so.
01:49Now the most obvious of the Fill Opacity blend modes, is Hard Mix.
01:53So again with that Assyrian layer selected, I'll go up to the Blend Mode pop-up
01:57menu and change it from Normal to Hard Mix and we end up getting this just
02:03absolutely hideous effect here.
02:04We are just left with eight colors, nothing more, by which I mean black, white,
02:08we also have red, green and blue as well as cyan, magenta, and yellow.
02:13Every single pixel is one of those eight colors and that's all we have left.
02:17So we've got this terrific degree of posterization.
02:20You might figure well, maybe we can tone the effect down a little bit by
02:24reducing the Opacity value.
02:25So I'll press the 5 key to reduce the Opacity to 50% and we end up getting a
02:3050/50 mix of the effect we saw just a moment ago along with the background image
02:35which, by the way, looks like that.
02:37So the result is a pretty poor effect in my opinion.
02:40Let's compare that to the exact same blend mode set to a Fill Opacity value.
02:44So I'll go ahead and click into right- hand image, change the Blend Mode from
02:48Normal to Hard Mix once again and then this time, I'll press Shift+5 to reduce
02:53the Fill Opacity to 50% and we get an entirely different effect with much
02:59smoother, more organic transitions. All right!
03:02Let's take a look at a few others.
03:03I am going to click in the left hand image once again, change the Blend Mode
03:06from Hard Mix to Color Burn, which is one of the Darken modes.
03:10We end up getting this dim grim effect on left.
03:13Click in the right-hand image, change it this time to the Color Burn mode as
03:17well and thanks to the fact that it's the Fill value that's set to 50% as
03:22opposed to the Opacity value, we end up getting what is still a very dim effect,
03:26but a better result. All right!
03:28Now I'll click in the left-hand image.
03:30Let's see Color Burn's opposite which is the middle mode in the Lighten group,
03:33Color Dodge, and then I'll click in that right-hand image and change it from
03:37Color Burn to Color Dodge as well.
03:40Now this time, the two effects are little more similar than what we've seen in
03:43the past, but notice over here on the left-hand side, we have a series of
03:47posterization, that is the sort of flat light grays that are going on here, in
03:52the cheek and along the nose, whereas that same region over here in the
03:56right-hand image provides us with a lot more detail.
04:00Just one more effect, I am going to click in the left-hand image once again.
04:03Let's change the Blend Mode this time to the first of the Inversion modes,
04:07which is Difference and notice that we do indeed invert certain details of the
04:11image particularly, those portions of the image that lie in the shadow region of the carving.
04:17Compare that to, if I go ahead and click in right-hand image and change its
04:21Blend Mode from Color Dodge to Difference, this time we get what appears to be
04:25an entirely different blend mode and yet, the only difference because we're
04:30still working with the Difference mode is that the Fill Opacity as opposed to
04:33the Opacity value is set to 50%.
04:36So hopefully, that gives you a sense of what's going on.
04:39I don't expect you to remember which modes are part of the Fill Opacity
04:42Eight and which aren't.
04:44However, I do want you to know that if you end up applying a blend mode and
04:48you get too heightened of an effect, it's entirely possible that you can rein
04:52it back more successfully using Fill as opposed to Opacity here inside the Layers panel.

Blending adjustment layers
00:00Another basic concept of blending in Photoshop has to do with adjustment layers.
00:04The idea is that in addition to using an adjustment layer to modify the
00:08luminance or color of an image, you can blend that adjustment layer which has
00:12the effect of blending the entire image or composition with itself.
00:17Consider this photograph.
00:18It's called Friends on chairs.jpg, found inside the 01_intro folder;
00:22great energy, wonderful composition as well, but the image is a little washed out.
00:27Now there is an old technique that goes like this.
00:29You start with your background item here inside the Layers panel and then you
00:33press Ctrl+Alt+J or Command+Option+J on the Mac to bring up the New Layer dialog box.
00:38Let's call this layer copy, click OK and now we have two copies of the image.
00:43Now if we were to assign a blend mode to that copy, we would effectively blend
00:48the image with itself and in our case, we need to darken up the image.
00:51So the most obvious example as you'll learn once we get into the Darken modes,
00:56is Multiply which is the when-in- doubt darkening mode inside Photoshop.
01:00Notice that we end up producing this effect here, which is absolutely great.
01:04We are keeping the detail inside of the shadows, we're darkening up the midtones
01:08quite nicely and we're doing so without losing any of the highlights.
01:12However, here's the problem.
01:14Take a look at these values down here in the lower-left region of the window.
01:18You'll see that the original document size, the value before the slash was
01:226.52 megabytes and the value after the slash is 13 megabytes, it's that second
01:28value that's the problem.
01:29The second value, the one after the slash shows you how big the image is with
01:33all of its layers and so by virtue of the fact that we created this copy layer,
01:38we effectively doubled the size of the composition.
01:41We just don't have to do that.
01:42So what I am going to do is press the Backspace key or the Delete key on the Mac
01:45in order to get rid of that copy and instead, we're going to do the exact same
01:49work with an adjustment layer.
01:51So I'll go ahead and press the Alt key or the Option key on the Mac, drop down
01:54to the black-white icon at the bottom of the Layers panel and choose
01:58Brightness/Contrast.
01:59Now really, you can choose anything from Brightness/Contrast down to Channel
02:03Mixer as long as you don't modify any of the settings.
02:06I tend to work with Brightness/Contrast, however, just because it's an obvious way to go.
02:11And because I had the Alt or Option key down that brings up the New Layer dialog
02:14box and I'll go ahead and call this layer dummy and then I'll click OK and that
02:19tells me that it's just an empty dummy layer, in other words, I haven't modified
02:23any of the settings, although I could later on if I wanted to.
02:26Now I am going to double-click to the right of the word Masks in order to
02:29collapse the Adjustments panel and I'm going to change the Blend Mode of that
02:33adjustment layer to Multiply, and we'll get exactly the same effect.
02:37Now you might look at that and say well, that doesn't really make any sense,
02:40why does it happen?
02:41Why does applying a blend mode to emptiness give you anything?
02:44Well, the way Photoshop figures it is when you apply a blend mode to an
02:47adjustment layer, you're applying that blend mode to the overall composite image.
02:52So in this case, we're multiplying the original photograph by itself and as a
02:57result, we get the exact same effect we got a moment ago, except that if you
03:00drop down to these values, into the bottom-left corner of the window, you'll see
03:03that the first value is as before 6. 52 megabytes and the second value which
03:09represents the size of the image with layers is also 6.52 megabytes.
03:14So we created a file that's going to be smaller in memory, more efficient and
03:18smaller in terms of file size as well.
03:20I'll give you another example here.
03:22I have this image called Low contrast butterfly.jpg, again found inside
03:26that 01_intro folder.
03:28I'll go ahead and once again press the Alt key or the Option key on the Mac,
03:31click the black-white icon, choose Brightness/Contrast, as I say it's my go-to
03:35adjustment for this kind of thing.
03:37Then I'll enter dummy as the layer name, click OK, go ahead and collapse
03:41the Adjustments panel.
03:42Whenever you see a washed out image, Multiply is a great place to start.
03:46So I'll go ahead and click on the Blend Mode pop-up menu and choose Multiply in
03:50order to darken up that image.
03:52The problem is this time around, we are ending up with a pretty dark image
03:56and it seems to me that we're losing some of the spark associated with the highlights.
04:00So now if I were concerned the image is darkening up too much and I wanted to
04:04brighten it overall, then I could switch to the best of the Lighten modes, which
04:08is Screen, however that ends up giving us a very washed out effect indeed.
04:12What we need is a heightened contrast effect, so I'll go ahead and click in the
04:16pop-up menu once again.
04:17This time I'll choose the foremost contrast mode which happens to be Overlay and
04:23we end up achieving this wonderful effect again without increasing the size of
04:27the file as you can see down here in the lower-left corner of the window.
04:31So this is the before version of the image and this is the after version;
04:35thanks to your ability to blend an entire image or composition with itself
04:40using adjustment layers.

Blend mode shortcuts
00:00Now of the amazing things about Blend modes is that just about every single one
00:05of them, 23 out of the 27 modes, include keyboard shortcuts and there are even
00:10some shortcuts for some modes I haven't told you about so far.
00:14So in this exercise, we'll walk through all those shortcuts.
00:17If you're not all that interested in shortcuts, great!
00:19Go ahead and skip to the next chapter.
00:21If you like shortcuts, however, go ahead and open up the file called Blend mode
00:24shortcuts.psd, it's found inside the 01_intro folder.
00:29Notice right off the bat here;
00:30we have shortcuts for switching to the next Blend mode or the previous Blend mode.
00:35So pressing Shift++ will advance get you to the next mode in the list, pressing
00:39Shift+- will take you to the previous mode and let me show you how that works.
00:43If I go ahead and click, let's say, on this highlights layer which is currently
00:47set to Multiply mode, if I press Shift ++, I'll advance to the Color Burn mode,
00:52which is next in the list.
00:53If I press Shift+-, I'll return to Multiply mode.
00:56That happens, by the way, because I have one of the selection tools active and
01:01that's how it works when any of the tools except for this second group of Paint
01:05and Edit tools is selected.
01:06If one of those tools is active, for example, if I switch to the Brush Tool,
01:11notice that the mode up here in the Options bar is set to Normal.
01:13If I press Shift++, I'll advance to Dissolve, if I press Shift+-, I'll return
01:18to the Normal mode.
01:20So just bear in mind that's how it works.
01:22Any time one of these Paint or Edit tools is selected, you're going to affect
01:26the mode assigned to that tool.
01:29The other really important thing to remember for those of you, who are
01:32working on the PC, is that you can deactivate the selected mode by pressing the Escape key.
01:37So let's say, I go over here to the Blend mode pop-up menu and I manually
01:42choose the Normal mode.
01:43It ends up being sticky as you can see here and that can prevent you from taking
01:49advantage of other keyboard shortcuts.
01:50For example, at this point, if I press the 5 key in order to reduce the Opacity
01:55to 50%, nothing happens because this darn Blend mode is active.
01:59So what you have to do is press the Escape key in order to deactivate it here on the PC.
02:04That is only a PC problem;
02:06you Macintosh people are just fine.
02:08All right, I am going to press Ctrl+Z or Command+Z on the Mac to reinstate the
02:12original Blend mode.
02:13Now let's take a look at the Blend mode specific keyboard shortcuts, all of
02:17which involve you pressing Shift+Alt here on a PC or Shift+Option on the Mac
02:23along with the letter key here inside the list.
02:26And again, that's going to affect the active layer assuming that any tool except
02:31for a Paint or Edit Tool is selected.
02:33If a Paint or Edit Tool is selected, you'll end up changing the mode assigned to that tool.
02:38Now many of the keyboard shortcuts make sense.
02:42For example, for Normal, you just press Shift+Alt+N or Shift+Option+N on the Mac.
02:46That's a good one to keep in mind, by the way.
02:48I definitely recommend you memorize it because it's really handy to be able to
02:52return to Normal by pressing Shift+Alt+N or Shift+Option+N on the Mac as opposed
02:56to manually choosing the mode from a list.
02:59Now I should say that I don't necessarily recommend that you memorize all
03:02of these shortcuts.
03:03I never have, for example, I can't keep track of them all.
03:06There is just no reason to, because you won't be using most of the Blend modes
03:10often enough to need shortcuts.
03:12So what I've done is I've gone ahead and circled each one of the shortcuts that
03:17I think is worth memorizing.
03:19And I've even gone ahead and provided mnemonics for all of the shortcuts in the
03:24event that they're not obvious just to help you out.
03:28Another obvious one, by the way, is Shift+Alt+M or Shift+Option+M for Multiply
03:32as well as Shift+Alt+S or Shift+Option+S for screen.
03:36Those are two really great Go To modes as we'll see.
03:41Any time you want to burn one layer into another, Multiply is the first
03:46and foremost way to go.
03:47Any time you want to use a layer to lighten the one below it, then Screen is
03:52the best way to go.
03:53So bear those two in mind.
03:54Now if you want to up the effect, for example, you want something that's darker
03:59than Multiply and has dare I say a little more pizzazz associated with it, then
04:04you'll most likely skip Color Burn and go to Linear Burn.
04:07But its keyboard shortcut is not obvious.
04:10Now I'll tell you, I've come up with different ways to memorizing this over
04:13the years, but the one that is stuck for me is that it really has the wrong shortcut.
04:18It has a shortcut of Shift+Alt+A or Shift+Option+A on a Mac which should have
04:22been assigned to Linear Dodge ( Add) which is its opposite effect.
04:27So it ends up getting the opposite of keyboard that it should've gotten and as I
04:31say that is the memory trigger that has worked for me.
04:34Now if you are interested in upping the Blend mode from Screen to something even
04:38brighter, then you'll probably skip Color Dodge down to Linear Dodge which has a
04:43keyboard shortcut of W which doesn't make any sense unless you think of it as
04:47being two upside down As, A for Add once again. All right!
04:52I am going to go ahead and scroll down the list to the Contrast modes and those
04:56first three Contrast modes are extremely useful.
04:59The one that you'll go to most often is Overlay which has an obvious shortcut of
05:04Shift+Alt+O or Shift+Option+O on the Mac.
05:07Next, we have Soft Light which is a more subtle contrast mode.
05:10It has a keyboard shortcut of F. After all, S is already taken by Screen, so
05:15we've got F which is the third letter in the word Soft.
05:19Then next we have a Blend mode that is kind of an upside down version of Overlay.
05:23You'll see how it works, very useful.
05:25It provides a little more contrast than Overlay does and it has an obvious
05:29keyboard shortcut of Shift+Alt+ H or Shift+Option+H on the Mac.
05:33Now if you want the ultimate degree of contrast, then you'll skip Vivid Light
05:38and go all the way down to Linear Light here which has a keyboard shortcut of J
05:42which is a backward L, that's all I've ever thought for it.
05:46Unfortunately L which you would hope it would get has been assigned to Hard Mix
05:52which is not a Blend mode you'll use very often, but you can think of it as
05:55being that ultimate mode in the fill opacity eight.
05:58Next, we've got Difference;
05:59very useful mode as we'll see.
06:01It has a keyboard shortcut of E, which is the last letter in Difference, because
06:05D got assigned to Color Dodge.
06:07And then finally, down here at the end the list, notice that we have Hue,
06:12Saturation, Color, and Luminosity.
06:14I recommend that your member that the keyboard shortcut for Hue is U. So
06:20Shift+Alt+U or Shift+Option+U on the Mac and that only figures because if you
06:24press Ctrl+U or Command+U on a Mac, you get the Hue/Saturation command.
06:29Then if you want to apply Color, a very useful mode indeed then you press
06:32Shift+Alt+C or Shift+Option+C on a Mac, that's pretty obvious and then
06:36finally, Luminosity;
06:37another great one, it's the opposite of Color as we'll see once again.
06:41Then you press Shift+Alt+Y or Shift+ Option+Y on a Mac and that's the last
06:45letter in Luminosity.
06:46Now I've also gone ahead and included the other Shift+Alt or Shift+Option
06:51keyboard shortcut variations that are available to you.
06:54They only work, however, when specific paint or Edit tools are active,
06:59especially the Brush Tool.
07:01So all of these shortcuts affect the Brush Tool and if you press Shift+Alt+P
07:05or Shift+Option+P on the Mac then you switch to the Airbrush Mode which is not a Blend mode;
07:10it's just an option associated with the Brush and some of the other tools.
07:13And then we have two, I guess, you would call them Blend modes, we'll see how
07:17they work in a couple of chapters.
07:19But we've got the Behind mode which has a shortcut of Shift+Alt+Q or
07:23Shift+Option+Q on a Mac, I don't know what to tell you about that, it's the
07:25letter after P. And then we've got the Clear mode, which allows you to treat a
07:29tool like an eraser and it has a shortcut of Shift+Alt+R or Shift+Option+R which
07:34is the last letter in Clear.
07:35But, as you can see, I haven't bothered to circle any of these shortcuts,
07:39because I don't consider them to be worth memorizing. All right!
07:43That's it, folks.
07:43Those are the shortcuts that are available to you.
07:46In the next chapter, we are going to talk about the math behind blending inside Photoshop.
07:52If you don't want to know about the math, then go ahead and skip that chapter in
07:56which case, I'll show you how to use the Normal modes.

2. The Revelation of Blending Math
The power of standardized arithmetic
00:00Now as I mentioned at the outset of the course, this chapter is devoted to the
00:04underlying math associated with blending inside Photoshop.
00:08A few of you are going to find this information to be terribly useful, many of you are not.
00:14If you have any hesitations whatsoever, if you feel like the math is just going
00:18to overwhelm you or get in your way of understanding what's going on, then by
00:22all means skip ahead to the next chapter which is when we get down to the
00:25creative business of blending inside Photoshop.
00:28And do so knowing that skipping these movies will not adversely affect your
00:32understanding of this course one iota.
00:35However, if you have a mind for math and you feel like learning what's going on
00:39under the hood inside Photoshop might help you out, then stick with me.
00:43I'm working inside this file called Standardize arithmetic.psd and I've created
00:48a few layer comps in advance.
00:50I am going to go up to the Window menu and choose the Layer Comps command and
00:53then I am going to click the right pointing arrow head in order to switch to the
00:57next comp and hide that warning text.
00:59And notice that I have the Assyrian layer selected here inside the Layers panel.
01:03I am going to bring up the Blend Mode pop-up menu.
01:05Now I want you to note that a few of the blend modes are named after their
01:10underlying arithmetic operators.
01:12For example, we've got Linear Dodge ( Add) which actually does add luminance
01:17levels to each other.
01:18So not surprisingly, we end up brightening the image considerably.
01:23And if the sum of any two pixels that is a pixel on the active layer and the
01:27pixel directly below it on the background layer, if that sum ends up being
01:32anything more than 255 for white, then it blows out, it gets clipped so we have
01:37a ton of clipping going on inside the image.
01:40The opposite blend mode is Subtract and so if you choose Subtract what you end
01:44up doing is you're subtracting the luminance levels on the active layer from
01:48those on the background layer and not surprisingly, we end up getting a very
01:53dark image and many of the composite pixels are now clipped to black.
01:57When things end up turning out differently than you might expect, is when we
02:01Multiply and Divide.
02:03So if I choose the Multiply blend mode, which you would naturally expect, if
02:07we're actually multiplying luminance levels, which we are, then you might
02:11expect the image to become lighter, instead it not only grows darker, but it
02:16grows darker uniformly.
02:18We have no clipping going on whatsoever.
02:21The Multiply mode never clips luminance levels unless they were already
02:25clipped in the first place.
02:26So in other words, there is no overly bright whites and there is no overly dark blacks.
02:31Next, if I switch to the opposite mathematical operator which would be Divide,
02:35we end up brightening the image like crazy and once again, we are clipping
02:41pixels all over the place.
02:42So what in the world gives?
02:44Well, I am going to go ahead and switch back to the Normal mode here and bring
02:48up that Layer Comps panel once again and advance to this next comp, Luminance
02:53levels and this brings us to our first slide which explains how you might
02:58naturally expect things to work inside Photoshop.
03:01So, let's imagine that as usual a luminance level of 0 is black and a luminance
03:07level of 255 is white.
03:08That's how it is throughout Photoshop, and luminance levels for the most part do
03:13work on a channel by channel basis, by the way.
03:15So where're we working with values greater than 1 that is 1 all the way up to
03:20255, then here is how things would go.
03:24Now you need to bear in mind that all blend modes rely on basic arithmetic
03:28operations that is Plus, Minus, Times, and Divide.
03:31They may mix and match those operations ever once in a while, but every single
03:35blend mode uses basic arithmetic.
03:38When working with values greater than 1, division usually delivers the smallest
03:42results, meaning we would get the darkest composite image, then subtraction,
03:46addition and ending with multiplication is the top dog.
03:50So, if you were to multiply, you'd get a very bright image.
03:53For example, let's say we have two pixels, one with a luminance level of 204
03:57which would be quite bright and the other with a level of 76 which would be very dark.
04:03If we were to divide and let's say the 204 pixels on the background layer,
04:07because that's how it would work then 204 divided by 76 would give us 2.68
04:13or very nearly black.
04:14That would be a very, very dark composite pixel.
04:17Subtract would give us 204 minus 76 which equals 128, which is, by the way, medium gray.
04:25If we were to add the pixels, we'd get 204+76 which would give us a level of
04:29280 and since 255 is white that's beyond white so that pixel will be clipped to white.
04:36Then where we'd to multiply those luminance levels, it would be 204 times 76
04:41which would be 15,504, which is extremely clipped.
04:46Well, I am here to tell you that's not the way it works.
04:49To see exactly how things do work, I am going to switch to my last layer comp
04:53and notice that it's titled working with values between 0 and 1. Here is a deal.
04:59Blend modes use standardized value, and by that I mean, all the luminance levels
05:03where blend modes are concerned fit inside that 0 to 1 range.
05:07So to figure out what the standardized value is, you just take the luminance
05:11level and divide it by 255.
05:13So black as always is 0, because 0 divided by anything is 0.
05:17White would be 255 divided by 255 which is 1 and medium gray would be 128
05:24divided by 255 which is 0.5.
05:27Multiplication and subtraction decrease brightness while addition and division
05:32increase brightness.
05:33For example, in a standardized world, the pixel with a luminance level of 204 becomes 0.8.
05:40The one with a level of 76 is now 0.3.
05:43So if we multiply those two pixels, we get 0 .8 times 0.3 which is a lower number 0.24.
05:50That translates to a luminance level of 61, which is a darker composite pixel.
05:56If we subtract these numbers we get 0.8 minus 0.3 which is 0.5 just as
06:01before medium gray.
06:03So subtract works the same way as it would where we're working with luminance levels.
06:07Add does as well, 0.8 plus 0.3 gives us 1.1 which translates to a luminance
06:13level of 280, the same thing we saw before, so it's clipped and then division
06:18gives us 0.8 divided by 0.3 which is a bigger number 2.67, because all these
06:26tiny numbers fit inside this larger number a lot more times.
06:30That translates to a level of 261, which is exceedingly clipped.
06:35So as a result, Multiply darkens uniformly, by the way, no clipping at all.
06:40Subtract darkens and may result in clipping.
06:42Add brightens and may result in clipping as well and division brightens and
06:47almost always results in clipping.
06:50And that folks, is how the basic arithmetic operations work where blending is
06:54concerned here inside Photoshop.

Photoshop's blending formulas
00:00All right, gang! Now we are going to actually get into the underlying arithmetic formulas that
00:05are associated with the blending operations here inside Photoshop.
00:08And we're going to take it pretty easy because there's an awful lot of stuff
00:12going on, even if you like math, by the way.
00:14The file I have open is called Blend mode math.psd, it's found inside the
00:1902_math folder and you can see that we've got the blending functions listed over
00:23here on the left hand side, the pixel formulas are listed here in the middle and
00:28then I've also provided a description of each one of the formulas, because it's
00:31very possible that you might look at A+ B-1 and think, all right, but I don't
00:38have any idea what in the world that would possibly mean.
00:41So we'll walk through all of them here.
00:43Now I have tried to document every one of the blend modes, with the exception of four.
00:49Normal and Dissolve, because they don't use any special math, and then Lighter
00:53Color and Darker Color which are composite modes that are based on Lighten and
00:58Darken respectively and we'll see how they work later.
01:01And then finally, despite a lot of research, I was not able to verify the
01:05formula for Soft Light.
01:07None of the formulas that I found out there actually worked the way the Soft
01:10Light blend mode does.
01:12Anyway, with that in mind here's what's going on with every single one of these formulas.
01:16They are based on the letters A and B . A represents a pixel on the active
01:21layer, B represents that same pixel on the underlying layers that is to say in the background.
01:28So A is active, B is background and that's really all there is to that.
01:33Notice also over here where the descriptions are concerned, I have this
01:36little caution icon.
01:37Any of the blend modes that include those caution icons may and probably will
01:43result in some degree of clipping;
01:45either you'll be clipping to black or to white.
01:48Any of the blend modes that do not include caution icons can not clip.
01:53They will not introduce any form of clipping, so they turn out to be the safest
01:58and typically the most useful modes.
02:01We'll start off here with the basic Opacity formula.
02:04I've re-showed you this one at the beginning of Chapter 2 of my masking and
02:08compositing fundamentals course, but let's go ahead and review.
02:12You may recall that Opacity is represented by the Greek letter alpha which is
02:17where the alpha channel gets its name.
02:19And so to calculate Opacity, you multiply that Opacity value and you would
02:25standardize it as well.
02:26So 100% Opacity would be 1, 0% opacity would be 0, 50% opacity would be 0.5, and so forth.
02:36So you multiply the active pixel by the Opacity value and then you take 1 minus
02:42that Opacity value, 1-a, which is the inverse of the Opacity value.
02:47Any time you see 1 minus anything in these pixel formulas that means you're
02:52finding the inverse and in this case, we're multiplying the inverse of the
02:55Opacity value by B that is that background pixel.
02:59So if the Opacity was 70% it'd be 0.7 times A and then 1-0.7 would be 0.3 for
03:0630% B. So it'd be 70% of the active layer with 30% of the background layer;
03:13pretty easy to figure that one out.
03:15And all it is, is a percentage based pixel mix.
03:18It's as if we are mixing a beverage, let's say;
03:20it's 70% one ingredient and 30% of another. All right!
03:23Now let's take a look at the first darkening mode which is Darken.
03:27All it does is locate the darkest pixels.
03:29So in other words, where any single pixel is concerned, it tries to find the minimum.
03:35So if A is darker then A wins and if B is darker B wins.
03:39Whichever pixel is darker is the pixel that you end up seeing after you blend
03:44the images together, which means, you end up getting a lot of harsh transitions,
03:48not one you'll be using on a regular basis, but still, there it is.
03:52Multiply as I was saying totally great mode incapable of clipping as you can see
03:57over here, no warning.
03:58And all it does is multiply the two pixels together.
04:01We saw how that worked in a previous exercise, the product of that equation
04:06evenly darkens the composite image.
04:09Now I'm also including just one mode as it relates to interacting with the
04:14Opacity value, because I want to give you a sense of how that works.
04:18So let's say, we're multiplying the active layer and we're setting it to say 70% Opacity.
04:24In that case, we would start things off by taking the product of the two images,
04:28so we would multiply them together, and then Photoshop would treat that as a
04:32composite version of the various layers and it would multiply alpha times that
04:37composite and then mix it in with 1-a of the background.
04:42Notice there is nothing special going on here.
04:44That (1-a)B is the same as it was when we're working with the Normal Mode, let's say.
04:51So as a result, we would have, in our case, 70% of the multiplied image blended
04:56in with 30% of the background image and so we get a translucent product and
05:01that's the way it works across the board.
05:03So any time that you're mixing in Opacity along with a blend mode, you were
05:09multiplying the Opacity value times the blended image and mixing it with the
05:14opposite of the Opacity value assigned to the background.
05:18That gives you at least an introductory sense of how the math works where
05:21blending is concerned with Photoshop.
05:23In the next exercise, I'll show you more.

Darken formulas vs. lighten formulas
00:00In this exercise I'll show you the formulas for the remaining Darken modes and
00:04we'll also see the Lighten modes and how closely they're related.
00:08I'm still working inside that document Blend mode math.psd.
00:12Notice down here the Color Burn formula.
00:15Now this becomes the first one of what I consider to be kind of the brain
00:19twisters, but one that's a little hard to figure out when you see it for the first time.
00:23Anytime, however, you see 1- like this that means that you're
00:28inverting something.
00:29So in this case, we're inverting the background image and I do truly mean inverting.
00:33We're inverting all the luminance levels and then we are dividing that inverted
00:37background by the active layer which would normally give us a very bright
00:42effect, which is why Color Burn then turns around and inverts the entire thing
00:47with this 1- upfront.
00:49So, as you can see here, we get invert, divide, and invert.
00:53Not surprisingly, because divide is involved, we have a caution icon that's
00:57telling us there is going to be some clipping.
00:59And Color Burn is one of those modes that almost always results in
01:03clipping inside Photoshop.
01:04Next, we have Linear Burn which provides us with a simplified equation, we are
01:09still going to get clipping out of it, but we do get smoother results as well.
01:13So Photoshop starts by adding the pixels together, which would normally brighten
01:18the heck out of the image.
01:19Bear in mind that Linear Burn is a Darken mode which is why we have a -1 at the end.
01:26Any time you're subtracting 1, you're not inverting.
01:29Instead what you're doing is you're taking the wind out of the sails.
01:33So 1 is an awfully big number to subtract where a blend mode is concerned,
01:38because after all, if you subtract 1 from what would normally be a composite
01:42white pixel, it's going to become black.
01:44So you might think looking at this equation, well, how is it that anything
01:48survives, why doesn't the entire composite image become black?
01:51And the reason is that A+B often results in numbers that are larger than 1 and
01:57the sum may be as large as 2.
01:59So in any case, we add the luminance levels together and then we sink that sum
02:03in order to create a darker image.
02:05The next group of four modes here are the Lighten modes, starting with Lighten
02:10which just finds the maximum luminance level where pixels A and B are concerned.
02:14So whichever pixel is lighter ends up winning on a pixel-by-pixel basis.
02:19Next drop down to Screen and notice, if you will, that every one of these
02:25Lighten formulas actually includes the Darken formula inside of it.
02:29So right there we've got multiply at work inside of Screen.
02:35So we've got A+B, we go ahead and add those pixels together which gives us a
02:38very bright image indeed, but to avoid any clipping because Screen never clips
02:44luminance levels inside of Photoshop, it goes ahead and subtracts the multiplied result.
02:49So what's really happening here, just to give you a sense, because this is a
02:53simplified equation, what's really happening here is Photoshop inverts the
02:57background then it inverts the active layer, it multiplies them together and
03:02then it turns around and inverts the result.
03:04And so what that mean is Screen is absolutely the inverse of multiply;
03:09it is that awesome brightening mode that always delivers smooth results and
03:13never clips luminance levels.
03:15Next we have Color Dodge and notice this time around instead of inverting the
03:19background image, Photoshop goes ahead and inverts the active layer and then it
03:24divides the background by that inverted foreground.
03:28This time, however, because it does not invert the result the way that Color
03:32Burn did, we get a bright result because you may recall from a couple of
03:36exercises ago, division always results in brightness inside of Photoshop.
03:41So we are taking the background, we are dividing it by an inverted version of
03:44the foreground layer.
03:46As a result, we get a very bright image and of course, we get clipping.
03:50And then finally, one of the simplest equations of them all, Linear Dodge (Add),
03:54all Photoshop does is it adds the luminance levels across the board on a
03:58pixel-by-pixel basis and because those values are frequently going to add up to
04:02more than one, we get clipping in some portions of the composition.
04:07So that's how the Darken and Lighten modes work and in next exercise, we'll take
04:11a look at the more complicated contrast modes.

Contrast mode formulas
00:00In this exercise, we're going to take a look at the more complex contrast
00:04formulas and you can see that I've gone ahead and scrolled down inside this
00:07file, Blend mode math.psd and I've also assigned these formulas a slightly
00:11different color scheme just so you can tell them apart.
00:14Almost all of the contrast modes involve an if-then proposition.
00:19Notice if the pixel is lighter than 50 % gray, then Photoshop does one thing;
00:24if it's darker than 50% gray, it does something else.
00:27So in the case of Overlay, which is your when-in-doubt contrast mode, Photoshop
00:32is concerned with the luminance of the background pixel.
00:35So if the background pixel is light that is its standardized value is more than
00:390.5 then it goes ahead and applies a kind of modified screen formula.
00:44Notice we have the A+B-(A?B) just as we do up here for screen, but we also have
00:50this 2? multiplier which goes ahead and brightens it and then Photoshop turns
00:54around and sinks the brightness by subtracting 1.
00:57The reason it does this is because it needs to fade that Screen effect.
01:02Bear in mind that when you apply Overlay or any of the other contrast modes, you
01:06need to somehow reconcile the fact that you're brightening the brightest pixels
01:10and you're darkening the darkest pixels.
01:12And you don't want there to be the sudden transition in between which is what
01:16you'd get if you just used the standard Screen formula.
01:19So in order to make sure that the midtones drop away, so the brightest color is
01:25still going to be very bright, the darkest colors will still be very dark, but
01:28anything that's a midtone on the active layer is going to slowly fade away and
01:33Photoshop accomplishes that with that 2 ? multiplier and that -1 at the end.
01:38Similarly, if the background pixel is dark that is less than or equal to 0.5,
01:44then Photoshop goes ahead and multiplies those pixels and adds the 2? multiplier
01:48as well in order to create the fade.
01:50So think of it this way;
01:52imagine that both A and B are 0, so they're black.
01:57Well, even if you multiply them times 2, they are still black.
02:00So black is always nice and black.
02:02It's those colors as they slowly become brighter and brighter that 2? multiplier
02:08ensures that they brighten up so that the midtones as I was saying, drop away so
02:12we get a fading multiply effect.
02:14Now you might suspect well gosh!
02:16Doesn't it go too far at some point?
02:18With the 2? multiplier that seems like a lot.
02:20Imagine that A is 0.5, so it's right there at 50% gray which turns
02:25invisible after all.
02:26Well, 2?0.5 gives you 1.
02:29So it's just 1 times luminance level of the background pixel which is why you
02:34see the background pixel;
02:35you do not see any of the foreground pixel.
02:38So that's how it works.
02:39For Soft Light, notice that I have if A . . . Well, what that's telling us is
02:44that we're concerned about the brightness of the active pixel, not the
02:47background pixels, as in the case of the Overlay mode.
02:50In fact, all of the other contrast modes are concerned with the brightness
02:54of that active pixel.
02:56However, I don't know what the precise formula is.
03:00I found about ten formulas online I should tell you and Adobe, by the way, does
03:03not share this information.
03:05That's why I had to go out there and try to seek it from other folks.
03:08But unfortunately, I conducted a test on every single formula I found and
03:12they just did not work.
03:14So it's some kind of complicated formula.
03:16It seems to be the most complicated of the bunch, but what we know is that Soft
03:20Light is a weak commuted overlay.
03:22And by commuted, I mean we are concerned about the brightness of the active
03:26layer pixel and not the background pixel.
03:28I'll explain more about that in a moment.
03:30By weak, I mean that where as Overlay treats white and black as absolute
03:36brighteners and darkeners, but Soft Light mode does not.
03:39So anything that's white or black inside the active layer will be translucent to some extent.
03:46I do want to emphasize something.
03:47No matter what formula actually exists for Soft Light, it is not merely a
03:52reduced opacity version of Overlay.
03:54That's just not true.
03:56It is an absolutely unique but more subtle effect. All right!
03:58Next, we've got Hard Light.
04:01Notice that Hard Light uses exactly the same equations as Overlay.
04:05So there is our brightening equation that same variation on Screen, there is the
04:08darkening equation that same variation Multiply.
04:11The only difference is that we are concerned with a luminance of the active
04:14layer, not the layers behind it.
04:17And that means that Hard Light is identical to Overlay were you to reverse the
04:21layer order, you would get exactly the same result.
04:24And that is the definition of a commuted blend mode, by the way.
04:28So Overlay and Hard Light are commuted versions of each other, just in case you
04:33ever hear that bandied about. All right!
04:34Next we have Vivid Light.
04:36Vivid Light is again concerned with a luminance level of the active pixel that
04:40is the pixel on the active layer and if that pixel is brighter then we end up
04:45applying a variation on the Color Dodge effect.
04:49So you may recall that Color Dodge inverts the luminance levels on the active
04:52layer and then divides them by the background layer.
04:56In the case of Vivid Light, we take 2-2A, so it's still and version but it's two
05:01times the inversion and then we divide that by the background layer.
05:06And the whole reason we have that 2? multiplier once again is so we can get a
05:10fading version of the Color Dodge effect.
05:12So we still have that over-the- top clipping, hence the warning.
05:17However, the lightening effect and the darkening effect come together and
05:20fade seamlessly into each other toward the midtones, which as always turn transparent.
05:26So that's something to bear in mind about all the contrast modes, 50% gray on
05:30the active layer is always transparent.
05:32Next, if then active pixel is darker, why then we go ahead and take that Color
05:36Burn equation and we double the brightness of the pixel on the active layer and
05:40that creates a fading Color Burn effect.
05:42Linear Light is interesting in that it's the only contrast mode that does not
05:47require an if-then proposition.
05:49What we're doing is effectively merging the two equations.
05:52So you may recall Linear Dodge is A+B and then Linear Burn is A+B-1 and then we
05:58take Linear Burn and we double the luminance of the pixels on the active layer
06:04and that works whether we are working with bright pixels or dark pixels.
06:07So it's an automatic fusion of Linear Dodge and Linear Burn into one equation
06:13and of course, it results in clipping.
06:15To make sure work of things here, Pin Light is a fusion of the Lighten and Darken modes.
06:20So we are trying to find the max value if the pixels are bright, but instead of A, it's 2A-1.
06:27So it's a kind of inversion, but not quite.
06:29And then if the pixel is dark, we're finding the minimum of 2A or B. And
06:35the whole reason we have the multipliers in there is to ensure that the
06:38midtones drop away.
06:40So one way it's lightened with modified midtones and the other way it's darkened
06:44with modified midtones.
06:45And then finally, we have Hard Mix, which is a derivative.
06:48What do I mean by that?
06:50Well, Photoshop takes the result of the Vivid Light mode and then it looks at
06:56each one of the independent color channels and it changes all the pixels in
07:00those channels to either black or white and when those channels merge together,
07:05so we have a red channel with just black-and-white pixels, we've got a green
07:08channel with just black-and-white pixels and we have a blue channel with just
07:12black-and-white pixels and that ends up giving us a total of eight colors in the
07:16full color composite image.
07:18And that, my friends, is what's going on with the contrast modes inside Photoshop.
07:22In the next exercise, we'll walk through the inversion, cancellation
07:26and component modes.
Collapse this transcript
Inversion, cancelation, and HSL
00:00Let's take a look at the rest of the formulas beginning with the one for the
00:03first inversion mode, Difference.
00:05Difference uses subtract.
00:07So we're subtracting the luminance levels of the active layer from those of the
00:10background layer and then we find the absolute value.
00:14So in other words, the result is always positive no matter what and that's
00:18why we end up getting an inversion result is because the numbers bounce back essentially.
00:24The composite luminance levels end up growing ever darker and then they bounce
00:27back and become brighter again.
00:30Exclusion, which is a very similar mode, it looks a lot like difference except
00:33it has lower saturation values, there is a lot of graze in the composite image.
00:38It uses a completely different formula that's based on the screen formula.
00:43So we're taking A+B just as we do with screen and we're subtracting AxB which is
00:48that multiply, but then we're multiplying that multiply formula by 2 and that
00:54creates another kind of bounce back.
00:56So colors that are very different from each other become bright and colors that
01:00are very similar to each other become either gray or very dark.
01:04So the bright colors doubled back and again, we get an inversion effect.
01:10Now these next two modes subtract and divide, they were introduced recently in Photoshop.
01:14However, they were actually already available inside the program, the
01:18variations on existing modes.
01:20So Subtract just goes ahead and subtracts A from B. That's it, but it turns
01:24that to be the same thing as inverting the active layer and applying the Linear Burn mode.
01:29And so as a result, it's very likely we'll get clipping.
01:32Divide goes ahead and divides the luminance levels on the active layer by
01:36those on the background and it's the same as inverting a layer and applying
01:41the Color Dodge mode.
01:42So again, they're not unique modes, but they can be useful every so often,
01:46especially where masking is concerned.
01:48Then we've got the component modes;
01:50Hue, Saturation, Color, and Luminosity and they don't really have equations.
01:54They're just mixes of the various primary components that are going on between
01:59the active layer and the background layer.
02:02So in the case of Hue, we're keeping the Hue from the active layer and mixing it
02:06with the saturation and the luminance of the background layer.
02:09In the case of Saturation, we're keeping the saturation of the active layer and
02:13mixing it with the hue and the luminance of the background.
02:16In the case of Color, we're keeping both the hue and the saturation of the
02:20active layer and mixing it with the luminance of the background.
02:24And in the case of Luminance, we do just the opposite.
02:27We mix the luminance of the active layer along with the hue and saturation of
02:32that background layer.
02:33And that's it, folks.
02:34That's how the underlying math works were blending is concerned inside Photoshop.
02:39It's a lot of stuff to know, I don't expect you to remember these formulas, but
02:43you can always come back to this document if you needed in the future and
02:46hopefully, knowing the mechanics of the mode will help you anticipate how they
02:50work as we employ the various blending options in future chapters.

3. The Normal Modes
Normal mode vs. Dissolve mode
00:00In this chapter we'll be taking a look at the normal modes.
00:03Now the first of the normal modes is Normal, which turns the Blend Mode off, not
00:07really anymore to say about that.
00:09The other modes are Dissolve, which I'll demonstrate inside this exercise.
00:13We also have a couple of other modes behind and clear that are associated
00:17with the Brush Tool and the Fill command and we'll see how those work in future exercises.
00:22I'm working in a file called Circles. psd found inside the 03_normal folder,
00:27and I'm going to start things off by switching the Blend Mode from Normal to Dissolve.
00:31You're not going to see much of a difference I'll go ahead and zoom on in here,
00:35so that we can see those edges, and you know what, I'll zoom to 200%, so you can
00:39see how things have gotten a little bit ratty along those edges.
00:43And what's happing here is, Photoshop is converting those edges to either
00:46absolutely opaque or absolutely transparent.
00:49So we're losing the anti-aliasing and then anti-alias edge is getting resolved
00:54as a dither pattern.
00:55Now it doesn't look much more than ratty at this point, let's go ahead and zoom
00:58back out by pressing Ctrl+ 0 or Command+0 on the Mac.
01:02If you really want to get a sense of what Dissolve is doing then try pressing
01:06for example the 5 key in order to reduce the opacity to 50%, and you'll see
01:11that instead of getting the standard expression of translucency which is what
01:15we get if we were looking at the circle in the Normal Mode and just for the
01:18sake of demonstration I'll press Shift+ Alt+N or Shift+Option+N on the Mac to
01:22switch back to Normal and now you can see that we have your everyday average 50% opaque circle.
01:27Alright, I'll press Ctrl+Z or Command+Z on the Mac to switch back to dissolve.
01:31So that's one way to exploit the Dissolve Mode, I'm going to press the 0 key in
01:36order to restore the Opacity to 100%.
01:39Here is something else you can do.
01:40Go up to the Filter menu and choose Blur and then choose Gaussian Blur and let's
01:46go ahead and increase that Blur value to something like 25 pixels and you can
01:51see that the entire blurred area, which is ultimately an expression of
01:54translucency turns into a dithered noise pattern.
01:57Now I'll go ahead and click OK in order to accept the effect.
02:01So that's the basics of what's going on with the Dissolve Mode.
02:04In the next exercise I'll show you how Dissolve becomes a more powerful Blend
02:07Mode when assigned to a Layer Mask.

Making a dynamic Dissolve effect
00:00So here I am looking at the Dissolved circle from the previous exercise.
00:04Now the problem with it even though it's surrounded by this interesting dithered
00:07noise pattern is that I can't back off the effect, because after all I applied
00:12Gaussian Blur as a static modification.
00:15So I can increase the Blur value if I want to, just by pressing Ctrl+Alt+F or
00:20Command+Option+F on the Mac to revisit the Gaussian Blur dialog box, and I
00:24could take the Radius value up to let's say 100 pixels to really blast things
00:29out and then click OK.
00:31But now I've applied another static helping of Gaussian Blur.
00:35Some other day when I'm working inside this file I can't back off the effect.
00:39What if you want to dissolve a layer dynamically?
00:42Well then you need to resort to a Layer Mask, and here's how.
00:45I'm going to turn off this Circle layer and I'm going to turn on the Mask layer
00:49which is a layer of solid white inside of a Layer Mask, so I'll go ahead and
00:53click on that Layer Mask thumbnail in order to select it and I'll once again
00:58switch from the Normal Mode to the Dissolve Mode and that will give us that
01:01slight amount of diffusion around the edge there.
01:04Then I'll bring up my Masks Panel by going to the Window Menu and choosing Masks
01:09and I'll increase the Feather value.
01:10So I'll take the value up to a 100 pixels for example in order to blow that
01:15effect away, and then later if I change my mind all I have to do is return to
01:20the Masks Panel and set the Feather value to something else, such as my original
01:24Radius value of 25 pixels, in order to achieve this effect here.
01:29Between you and me I consider this an extremely good way to work.
01:32I do want you to know however that while it works for pixel-based layer masks
01:37this technique for whatever reason does not work with vector masks.
01:41So I'll go ahead and turn off that mask layer, and I'm going to collapse my
01:44Color Panel just to give myself a little more room, and then I'll turn on the
01:47vector layer, click on its mask thumbnail in order to select it, change the Mode
01:52from Normal to Dissolve.
01:53Notice that we don't see any changes around the edges of that circle.
01:58Even if I increase the Feather value to something extreme such as let's say 100
02:02pixels we still end up with some very smooth transitions.
02:06So that's just my way of letting you know that if you want to work with Dissolve
02:09then you need to be working with the pixel-based layer or in this case a
02:13pixel-based Layer Mask.
02:14In the next exercise I'll show you how to use the Dissolve Mode to create an
02:18interesting text effect.

Creating a Dissolve text effect
00:00In this exercise I am going to show you how to create a custom text effect
00:03using the dissolved mode.
00:05Specifically we'll be creating the effect you see here and the name of the file
00:09by the way is Stress text.psd found inside the 03_normal folder.
00:14I'm going to switch over to this file, White type.psd.
00:17Notice that it contains an editable text layer.
00:19Now I'll start things off by applying the dissolve mode.
00:22So I'll switch from Normal to Dissolve like so, and we get those
00:25slightly dithered edges.
00:27Now to increase the fact we need to blur the text, we can't blur the text
00:31directly, so we first need to convert it to a smart object by going up to Layers
00:35panel fly-out menu and choosing Convert to Smart Object or if you loaded my
00:38DekeKeys, you can press Ctrl +, or Command+, on the Mac.
00:42Next I'm going to go up to the Filter menu choose Blur and choose Gaussian Blur
00:47and I'll take the Radius value up to 5 pixels, but the great thing here is that
00:51you can change your mind anytime you want.
00:53So after clicking OK, I could just double-click on Gaussian Blur here inside
00:58the Layers panel, in order to revisit the Gaussian Blur dialog box and I could
01:02reduce the Blur value to something like 2, and then end up with a modified effect.
01:06Anyway, I don't want to do that, I just wanted to show you, so I'm going to cancel out.
01:10Next we need to assign a Bevel & Emboss effect, but if we try to apply the
01:14effect directly to this dithered text, we want get the effect we're looking for.
01:17I'll go ahead and show you what I mean, I'll drop down to the fx icon and
01:21choose Bevel & Emboss and notice that we don't have a dithered emboss affect at
01:26all, instead we have this very soft emboss, and that's because the layer effect
01:30doesn't actually see these dithered edges, and so far as it's concerned, we
01:34still have those blurry edges from Gaussian Blur filter, so I'll cancel out of here.
01:38Here is what we need to do instead, we need to convert this text into a mask,
01:43and we're going to do that by turning off the redness layer.
01:45Notice that I have a layer of black in the background, so the text will select itself.
01:50All I have to do is go to the Channels panel and then Ctrl+Click or
01:54Command+Click on the Mac, on any one of these channels here.
01:58Either the RGB composite or the red green or blue channel, any of them will do.
02:03Now we've managed to select the text including those dithered edges, so I'll
02:07switch back to the Layers panel and turn the redness layer back on, turn our
02:11stress text layer off, and then press the Alt key or the Option key on the Mac,
02:16click on that black white icon down at the bottom of the panel, and choose
02:19Solid Color and we'll go ahead and call this layer static text, because that's what we have now.
02:25We're not going to be able to edit this layer as text in the future.
02:28I clicked OK, and by default Photoshop is going to want to fill the layer with
02:31black, that doesn't matter, just click OK to escape the color picker dialog
02:35box, because we're going to reduce the Fill value to 0%, and of course the text disappears.
02:41However, now we can throw layer effects on top of it.
02:44Go ahead and click on the fx icon down here at the bottom of the panel, choose
02:48Bevel & Emboss in order to bring up the Layers Style dialog box.
02:52Assuming default settings, take the Size value down to 3 pixels and then let's
02:56take both of the Opacity values up to 100 % and we end up with this subtle effect
03:01here, don't worry, it want end up being subtle by the time we're done, click on
03:04Drop Shadow in order to turn on that effect, and let's go ahead and crank the
03:09Opacity value up to 100% once again, and take both the Distance and Size value
03:13stand to 3 pixels and then click OK.
03:16Now I want to apply a few helpings of the mezzotint filter, which will create
03:20those horizontal grooves in the letter.
03:22To do so, click on the Layer mask icon to select it and then, because we only
03:27want the mezzotint lines to appear inside the letters, Ctrl+Click or
03:32Command+Click on the Mac on that layer mask thumbnail in order to convert it
03:36into a selection outline, then press Ctrl+H or Command+H on the Mac to hide the edges.
03:41Go to the Color panel and change your foreground color to 25% black, like so,
03:48and then press Alt+Backspace or Option+ Delete on the Mac to fill the letters
03:52with that very light shade of gray, and the reason we're doing that is we need
03:56to give the mezzotint filter a little grayness to lock onto.
03:59Then, go up to the Filter menu choose Pixelate, and choose Mezzotint, and inside
04:05the Mezzotint dialog box, switch the type from Fine Dots, which I believe is a
04:09default to the last setting in the list, Long Strokes and then click OK in order
04:15to create this effect here.
04:16Now if that's not quite enough for you.
04:18If you want up the effect a little bit, then press Ctrl+F or Command+F on the
04:22Mac to add a few more lines.
04:24I'm going to press Ctrl+F or Command+ F yet again in order to apply a third
04:28helping of the filter in order to achieve this effect here.
04:32Now the great thing about mezzotint is it's a random filter, delivers a
04:36different effect every time, so this is how my effect looks this time around,
04:39this is how it looked before.
04:41Thanks to our ability to exploit the dissolved mode for special effects purposes
04:46here inside Photoshop.

The Behind and Clear modes
00:00In this exercise I'll demonstrate the behind and clear modes.
00:03Both of which are part of the normal group, but they're not found inside the
00:07Layers panel, instead they're associated with a handful of the Paint and Edit
00:10tools as well as the Fill and Stroke commands.
00:13I'm working inside a file called Big blue marble.pds, found inside the 03_normal folder.
00:19Notice that the marble layer is selected here in the Layers panel and I've gone
00:22ahead and assigned a white stroke, just so we can easily keep track of the
00:25edges of this layer.
00:26I have also set my foreground color to red in advance, I'm going to go ahead and
00:31switch over to the Brush Tool, which I can get by pressing the B key, and armed
00:35with my walk on tablet, I'm going to go ahead and paint a brush stroke over the
00:39Earth like so, and so this is the effect of normal painting on a layer inside a
00:45Photoshop, and notice that the program went ahead and automatically traced the
00:49stroke around the new contours of the layer.
00:52Now let's say I want to paint exclusively inside the layer, I want to affect
00:56the opaque pixels, respect the transparency, so that I'm effectively painting inside the lines.
01:01Well, then I would go over to the top of corner of the layers panel and turn on
01:05the first lock icon, which locks down the transparent pixels, you can also by
01:09the way invoke that icon by pressing the slash key.
01:12So in my case, slash would turn it off and then slash would turn it back on.
01:16Now, if I paint somewhere inside the layer, I will paint my brushstroke
01:20exclusively inside the Earth or inside the existing red brushstroke.
01:26That's not technically speaking a blending option, I only bring it up,
01:30because what if you want to do exactly the opposite, instead of painting
01:34inside the opaque region of the layer, you want to paint exclusively in a
01:37transparent portion of the layer, then turn off that lock icon, that's very
01:41important, and then go up to the Mode option here on Options bar and switch
01:45it from Normal to Behind.
01:47So you will effectively paint behind the layer even though I should say you're
01:52still painting on the layer, you're just expanding the transparent region.
01:56What I'm going to do is press the Escape key, so that option is no longer active
02:00at the top of the window there, and then I'm going to press the DekeKey in order
02:04to make my foreground color black and notice now as I paint, I'm painting
02:08exclusively behind the Earth and that red brushstroke that I drew a moment ago.
02:14So that's how the Behind mode works.
02:16There is one more, and that's a Clear mode.
02:18If I switch the mode option from Behind to Clear, and notice that these two
02:23options are part of that first normal group, then I effectively turn my
02:27paintbrush into an eraser, so that I can erase lines into the world here.
02:33The effect here isn't any different than painting with the Eraser Tool, so it's
02:37kind of a duplicate effect.
02:39However, if you're using the Brush Tool and you want to erase on the fly, it's a
02:42convenient way to go.
02:44Remember that you have a keyboard shortcut for the clear mode, which is
02:48Shift+Alt+R or Shift+Option+R on the Mac.
02:51That's how the Behind and Clear modes work when combined with the Brush Tool.
02:55In the next exercise, I'll show you how to make use of both of those modes using
02:59the Fill and Stroke commands.

Filling a stroke with Behind and Clear
00:00In this exercise I am going to show you how to use the Behind and Clear modes
00:03along with the Fill and Stroke commands.
00:06I've gone ahead and restored the saved version of my Big blue marble.psd file,
00:10found inside the 03_normal folder.
00:13And very quickly, let me show you how the options work along with the Fill
00:16command just so you can have a sense of what's going on here.
00:19I am going to switch from the Rectangular Marquee to the Elliptical Marquee.
00:22Notice that I've already set my foreground color to Red in advance.
00:26I also have the marble layer selected inside layers panel.
00:28I am going to draw the circular selection around this side of the earth and then
00:33I'll go up to the Edit menu and choose the Fill command, or you can press a
00:37keyboard shortcut Shift+ Backspace or Shift+Delete on the Mac.
00:41I mention that because that's what I'll be doing in the future.
00:43We'll go and choose the Fill command.
00:45I've set Use to Foreground Color, so that I'm filling the selection with that shade of red.
00:50And I've got the Opacity cranked up to 100%.
00:52I am going to change the mode from Normal to Behind and then click OK and I end
00:57up filling the region behind the earth.
01:00Another thing you can do, if I were to move this selection to a different
01:03location and then return to the Edit menu, choose the Fill command again.
01:07I could change the mode from Behind to Clear and then go ahead and click OK and
01:13I'd cut a hole using that selection which is actually kind of a lot of work
01:17when you think about it.
01:17I'll press Ctrl+Z or Command+Z on a Mac, because all I had to do was press the
01:22Backspace key or the Delete key on the Mac in order to delete the pixels
01:25inside this selection.
01:27But it's a way of working.
01:28Anyway, let me show you something of a practical use for these modes.
01:32I am going to go up to the File menu and choose the Revert command in order to
01:35restore my saved world.
01:37And then I'm going to draw some rings around the planet like so.
01:40So I'll draw a big ring to start with and then I'll press the Alt key or the
01:45option key on the Mac in order to subtract a smaller ring from the inside.
01:50And notice that I'm cheating kind of up, so that the ring appears to decline as
01:56it moves away from us.
01:57All right, so the idea here is I want to create a bright red ring around the earth.
02:01I am going to press Ctrl+H or Command+H on a Mac in order to hide the selection
02:05and then I'll press Shift+Backspace or Shift+Delete on a Mac in order to bring
02:09up the Fill dialog box and I'm going to change the mode to Behind once again so
02:15that I fill the rings behind the earth and I'll click OK.
02:18Now that looks pretty good and we definitely want the big red ring to go
02:21behind the earth when it passes around the rear of the planet, but we need to
02:25see the ring in front here.
02:27So I'll press Ctrl+H or Command+H on the Mac to bring back my selection
02:30outline, so I cam see it.
02:31And I am also going to switch back to my Rectangular Marquee Tool, press
02:35and hold the Alt key or the Option key on a Mac and remove this portion of
02:40the selection like so.
02:42So, I am deselecting the area around the top of the planet, fairly roughly
02:47as you can see here.
02:47So I have this region still selected for the front of the globe and now I'll
02:52press Shift+Backspace or Shift+Delete on the Mac in order to bring up the Fill
02:56dialog box once again.
02:57This time I want to respect the Opacity of the layers, so that I am just
03:00filling in the portion of the selection that's already been filled in and that
03:04way I won't get any harsh transitions over here at the sides of the rings, the
03:08ones that I've cut off.
03:10So what I want to do is turn on the Preserve Transparency checkbox, because
03:13that's just like that Lock Transparency option in the Layers panel that we saw
03:17in the previous exercise, but it's dimmed and that's because the Mode is set to Behind.
03:21Any time the Mode is set to Behind or Clear that option will appear dimmed.
03:25However, if you change Mode back to Normal, it becomes available again.
03:29I'll go ahead and turn it on and then click OK in order to fill the forward part of the ring.
03:34All right, now what I want to do is scrape away the areas above and below the
03:40ring in the planet just as an effect and I am going to do that using the Stroke
03:45command combined with the Clear mode.
03:48So I'll go up to the Edit menu and I'll choose Stroke and notice those of you
03:52who loaded dekeKeys, I've given you a keyboard shortcut, I use this command all the time.
03:56It's Ctrl+Shift+' or Command+Shift+' on the Mac.
03:59Anyway, I'll go ahead and choose the command, I am going to crank the Width
04:02value up to 30 pixels, change the location to outside like so and then change
04:08the mode from Normal to Clear and click OK.
04:12And that goes ahead and creates these clear strokes above and below the rings.
04:16All right, now I am going to press Ctrl+D or Command+D on a Mac to deselect the image.
04:20Now, we've got some problems, we've got some breaks over here on the right and
04:25left hand sides of the rear rings.
04:27We'll reinstate those using the Rectangular Marquee Tool;
04:30just go ahead and select around one region, Shift+Select around the other
04:33region in order to make sure that both of the broken areas are encompassed
04:37inside your selection.
04:39Then I want to go up to the Window menu and choose the History command in order
04:43to bring up the History panel.
04:44And we want to set the source state to the one immediately before stroke and you
04:49do that by clicking in front of, in my case, Fill.
04:52So you'll see this little Brush icon in front of the state immediately before stroke.
04:56Once again, go ahead and hide that panel and then press Shift+Backspace or
05:01Shift+Delete to bring up the Fill dialog box, turn off Preserve Transparency,
05:06make sure Mode is set to Normal, Opacity is set to 100% and then change Use from
05:11Foreground Color to History and then click OK and that goes ahead and reinstates
05:17those missing pieces.
05:19And that, friends, is at least one way to combine the Behind and Clear modes
05:23along with a Fill and Stroke commands here inside Photoshop.

4. The Darken Modes
Darken vs. Darken Color
00:00In this exercise, we'll take a look at the most basic of the Darken modes which
00:04are Darken and Darker Color.
00:06Now between you and me you are not going to be using these blend modes very
00:09often, however I do want you to understand how they work and I will be showing
00:13you a couple of filtering effects that work quite nicely with the Darken mode
00:17in the next exercise.
00:18I am looking at a file called Darken demo.psd found inside the 04_darken folder
00:24and notice below the model layer, we have a trio of background layers that we'll
00:29be taking a look at over the course of next few exercises.
00:32We'll start things off by merging the model with this water layer in the background.
00:37All of these images by the way hail from the Fotolia Image Library about which
00:42you can learn more and get a discount at fotolia.com/deke.
00:44I am going to go ahead and turn that model layer back on, click on the Blend
00:49Mode pop-up menu and then choose Darken.
00:51Now this blend mode is extremely simple.
00:54Here's what it does.
00:55I am going to go ahead and zoom in here, so we can see things more closely.
00:58Darken evaluates every pixel on the active layer and compares it to the
01:02pixel directly behind it.
01:04If the pixel on the active layer is darker, then you see that pixel.
01:08If the pixel behind it is darker, then you see the background pixel instead.
01:13So it's an on-off proposition, either you're seeing the active layer pixel or
01:17you're seeing the background pixel.
01:19Now if you take a look at this image that doesn't really reconcile.
01:23After all there are some portions of her face that are definitely opaque here
01:27in the shadow region along the right side of her cheek and down her neck as
01:30well, and some of the shadow details inside of her lips, and her eyelashes, and so forth.
01:35And these other areas over here on the left hand side of the face that are
01:38giving way to the water in the background, but then we have some transitional
01:42areas where her skin ends up looking translucent to the point that emerges with
01:47the blue of the background in order to create these green shades.
01:51So what in the world is going on there?
01:52Well, that comparison I was telling you about, that on-off comparison, either
01:56you see the active pixel or you see the pixel behind it, is happening on a
02:00channel by channel basis.
02:02So if I switch to the Channels panel and click on the Red channel, you can see
02:05now that it is an on/off proposition, it maybe hard to tell in some of these
02:10semi-transitional areas here, but either we're seeing the red pixels from her
02:14face or we're seeing the red pixels from the water and that's it.
02:18There is no merging of the pixels, there is no translucency going on.
02:22However, because the water is blue, it's not very bright inside of the Red
02:26channel, so the water is usually winning out.
02:29If I switch to the Green channel, we're seeing a lot more of her face this time
02:33around, because the water has a lot of green in it, meaning, that the water is
02:37very bright in the Green channel, and she's darkening up inside the Green
02:40channel, and then when we switch to the Blue channel, she wins every pixel I
02:45believe, because after all blue water is going to show up very bright in the
02:49Blue channel and as a result, she's relatively darken to Blue channel.
02:53So the upshot is that these various channels intermix with each other and we end
02:58up with these transitional greens in between.
03:01Now if don't want that, if you want a strictly on/off proposition across the
03:05board, then you switch back to the Layers panel, click on that Blend Mode pop-up
03:09menu and select the last of the Darken modes.
03:12Now in my opinion, it ought to directly follow Darken, because Darker Color is a
03:16very similar mode, and it's not related to the three in between.
03:20However, you go ahead and choose Darker Color, and now what's happening is
03:24Photoshop is deciding whether a pixel is darker in the active layer or whether
03:28it's darker in the background on a composite basis.
03:31So in other words, we are ready to switch back to the Channels panel, we are
03:34seeing those same pixels show up as opaque in the Red channel, the Green channel
03:39and the Blue channel.
03:40So, all three channels are showing the same opacity information.
03:43In other words, either, we're seeing a pixel from the active layer or a pixel
03:47from the background, and that's it. All right!
03:49I am going to go ahead and switch back out, zoom out as well in order to take in the image.
03:53So you can see that Darker Color might prove useful on occasion if you are
03:58trying to create the effect that one image is emerging from another image, as
04:03we see here, however, you do get very harsh jagged transitions as a result of this mode.
04:10So Darker Color seeks out the darkest pixel on a composite basis, and Darken
04:15does so on a channel by channel basis.
04:18In the next exercise, I'll show you how to combine Darken along with Smart
04:21Filters to achieve a couple of special effects.

Creating filter effects with Darken
00:00In this exercise, we will explore a couple filtering effects that rely on
00:03the Darken Blend mode.
00:05I have restored the same version of Darken demo.psd found inside the 04_darken
00:09folder, and I am going to turn off the model layer and click on the water
00:12layer to select it.
00:14Now notice that the water is pretty bright and I actually brightened it up a bit
00:17using a layer effect.
00:19To see that effect, go ahead and click the down pointing arrow head to expand
00:22the effects and then double-click on Color Overlay to bring up the Layer style dialog box.
00:27And you'll see all it is, is a white overlay. That's it.
00:30So if I was to change the Opacity to 100%, the entire layer would turn white,
00:35which is why I reduce the Opacity to 35% and that just ended up boosting all the colors.
00:41Reason I did that was to keep things nice and bright so I could better
00:44demonstrate how those darken modes work.
00:45Anyway, it's just another way to brighten the layer.
00:48I am going to cancel out of that dialog box and I am going to turn off that
00:51effect because I don't want it for this demo.
00:53And then I'm going to click of the fly-out menu icon and choose Convert to Smart Object.
00:57In order to turn this into a smart object, so I can apply smart filters.
01:02Now let's say what I want to do is I want to fill in some of the whites in the water here.
01:06And I want to do so using a Blur effect, so we get kind of color softness going on.
01:11However, I don't want to lose the detail in the water.
01:14Well, I'd go up to the Filter menu, choose Blur and then choose Gaussian Blur.
01:19And in this case, I decided to take the Radius up to 10 pixels, but you can play
01:23around with out to see what works.
01:25Then click OK and next, drop down to this little slider icon right there,
01:29double-click on it in order to bring up the Blending Options dialog box.
01:33Smart filters are another instance where you have access to the entire list of
01:37those same 27 blend modes that are available to you in the Layers panel.
01:41And I am going to go ahead and choose Darken, in order to keep those blurred
01:44pixels that are darker than the original pixels.
01:47So in other words, if the blurred pixels are darker, we are seeing them;
01:51if the original pixels are darker, we are seeing them instead.
01:54Now as a result, we are seeing an awful lot of detail inside of this water.
01:58I will go ahead and click OK in order to accept that modification.
02:01And so that's just one example;
02:03you can try that out all kinds of different images.
02:05It tends to be quite useful for diffusion effects, especially on backgrounds. All right!
02:10Let's check out another one.
02:11I am going to go ahead and turn on the model layer and click on it to make it active.
02:15Let's convert it to a smart object as well by clicking on the fly-out menu icon
02:19and choosing Convert to Smart Object or if you've loaded dekeKeys, you can press
02:22Ctrl+Comma or Command+Comma on the Mac.
02:25And now I am going to go up to the Filter menu, choose Pixelate and choose a
02:29filter that I don't use very often, Mosaic.
02:31And if you know anything about this filter, what it does is exactly what you're seeing.
02:35It pixelates the image which can be useful on a practical basis, if you're
02:39trying to make somebody in the background unrecognizable, for example, you don't
02:43have a model release on somebody that you photographed.
02:46There's a behind some people that you do have model releases for.
02:49So you just go ahead and pixelate their eyes or their facial features that
02:52second kind of thing and Mosaic is the way to pull that off.
02:55I have set the Cell Size to 32 square.
02:58What that means is 32 pixels by 32 pixels square, for each one of these big
03:02pixels and then I'll click OK in order to accept that effect.
03:06Now in this case, I do want this to be an effect, I want the detail from the
03:10model to show through.
03:12So I'll go ahead and double-click on the slider icon in order to bring up the
03:15Blending Options dialog box and once again, change the mode from Normal to
03:19Darken and we end up with this effect here, which I think is pretty becoming.
03:24I will go ahead and click OK.
03:25Now imagine at this point, I will go ahead and zoom in here a little.
03:28I want to achieve some scalloped edges around the square.
03:32So I want these squares to have a little bit of roundness associated with them.
03:36So I will go back up to the Filter menu, choose the Noise command this time
03:40and then choose Medium.
03:42And I ended up arriving at a Radius value that is one quarter the value I
03:46entered into the Mosaic dialog box.
03:49So I entered 32 before, this time around I change the radius to 32 divided by 8 pixels.
03:55The math doesn't really matter that much, but I ended up liking the effect.
03:58So I will go ahead and click OK in order to apply the command.
04:01And then once again, we don't want to rub out all the detail in the
04:05underlying originals.
04:06So double-click on the slider icon to bring up the Blending Options dialog box
04:10and switch the mode from Normal to Darken in order to bring that detail back. Click OK.
04:15Now at this point, I figured she was sort of this computer rendering.
04:19So I ought to introduce some circuit board green and I did that by dropping down
04:24to the fx icon and choosing Color Overlay and not surprisingly, I decide change
04:29the Blend Mode for this effect to Darken and by default, you are going to get
04:33this highly saturated very bright red effect.
04:36Click on the right color swatch to bring up the Color Picker dialog box and then
04:39change the Hue value to 90 degrees like so.
04:42And then click OK and click OK again and we arrive at this final effect, which
04:48given the small amount of work we put into it, I think it's quite successful.
04:52And what's more amazing is it relies on two smart filters and a layer effect all
04:57of which are set to the Darken blend mode.

The Multiply and Burn modes
00:00In this exercise we will take a look at the three remaining darken modes,
00:03Multiply, Color Burn and Linear Burn.
00:06These are the ones that you'll be using on a regular basis, in particular
00:10Multiply, which is one of the big majorly used for blend modes inside Photoshop.
00:14I have restored the saved version of Darken demo.psd, found inside the
00:1804_darken folder and this time around we are going to merge the model with the
00:22Wall layer in the background.
00:23So I am going to turnoff both the travertino and the water layers.
00:27And you can see, we've got the Model layer selected, if I turn her off for a
00:30moment, there is the Wall layer that we will blending her against.
00:33I will go ahead and turn that layer back on and change the Blend Mode to Darken,
00:37just so you can get a sense of what that looks like.
00:39Now notice in this case, because she is a warm image set against a warm
00:43background, in other words, the pixel that's darkest ends up reconciling about
00:47the same way in each of the three color channels.
00:50So we have nothing resembling smooth transitions.
00:53Compare that to Multiply, if I were to press Shift++, that will advance to the
00:57next mode, which is the Multiply mode, and we've got these splendidly smooth
01:01transitions throughout the composition.
01:03Now by way of analogy, imagine that you have two transparencies;
01:08the model has been rendered on one transparency, the wall on another.
01:11You take both of them, you set them on a light table on top of each other, and
01:15this is the effect that you would get.
01:17The light is shining through both of the transparencies growing darker with
01:21the application of each, and as a result you end up getting a darker
01:24combination of the two.
01:26Here's something to know about the Multiply mode though.
01:28It never results in clipping, so in other words, you are not going to clip any
01:32pixels to white or black unless it was already clipped to white or black
01:36before you started.
01:38Multiply will not introduce clipping into the image, it can't, which is one of
01:42the wonderful things about the mode.
01:44And we will see a few applications for it in future exercises.
01:48If that's not quite the effect you're looking for, if it's too subdued for
01:51example, you can switch to one of the Burn modes, and we have got two of them to
01:55choose from, Color Burn and Linear Burn.
01:58Color Burn ends up producing a stark and highly saturated blend, as you can see here.
02:03It's almost as if the photograph of the model was burnt into the wall in the
02:07background, which can be great for creating special effects.
02:10However, you end up losing a lot of contouring as well, as you can see here.
02:14Color burn, because it's one of the over the top effects, it's part of the Fill
02:18Opacity, meaning, that it responds differently to the Fill value, than it does
02:22to the Opacity value.
02:23So if you're tempted to back off the effect, what I suggest you do is reduce
02:27Fill as opposed to Opacity.
02:30So for example, if I press Shift+8 in order to reduce that Fill Opacity value to
02:3480%, I end up achieving these more organic transitions.
02:38All right, I am going to press Shift+ 0 to restore the Fill value to 100%.
02:42And then I will advance to the next blend mode by pressing Shift++ and that
02:46blend mode is Linear Burn.
02:48Now notice that we lose a lot of the over-the-top saturation, which is a good
02:52thing in my opinion, I really like is mode, I use it a lot.
02:55And we also restore a lot of the detail on the left side of the model's face.
02:58Now just for the sake of comparison, I want you to see multiply, and I am going
03:03to use its keyboard shortcut, which is Shift+Alt+M or Shift+Option+M on the Mac.
03:08So that's the Multiply Mode, nice smooth transitions, but it doesn't necessarily
03:13have the impact of the Linear Burn mode, which has a keyboard shortcut of
03:17Shift+Alt+A or Shift+Option+A on the Mac.
03:20The thing you need to bear in mind about both the Burn modes however is that
03:24they can, and most often do introduce clipping.
03:28And if they're going to clip anything, they're going to clip the shadow details,
03:31meaning that some of the shadow details are going to get in black.
03:34And if you want to check out what those details are, then just go ahead and
03:38create a Levels Adjustment layer.
03:39I am going to click of the black- white icon at the bottom of the panel and
03:42choose Levels, and that will open up the Adjustment Panel.
03:46You can see here on the left side of the histogram that we've got a lot of
03:49clipping going on, because we have a big huge spike right there in black.
03:53If you want to check out where that clipping is occurring, press and hold
03:56the Alt key or the Option key and the Mac and click and hold on that black slider triangle.
04:01Any pixels that shows up is absolutely black, has been clipped in all three
04:06color channels, which is something of a dangerous thing potentially.
04:09Anywhere that you see any other colors showing up, meaning it's clipped in one
04:13or more color channels, White means no clipping is occurring.
04:17But just because clipping is not occurring at those locations, doesn't mean
04:21that you are going to be able to hold these very, very dark shadows when you go
04:24to print the image.
04:25So what you might want to do is click on that Model Layer again in order to
04:29select it, Linear Burn, like Color Burn is part of the Fill Opacity eight, so
04:34it responds differently, generally better, to the fill value, than it does the opacity value.
04:39I am going to press Shift+8 in order to reduce that Fill value to 80%, and now
04:43if I click on the Levels layer once again and press the Alt key or the Option
04:47key on the Mac and click and hold on that black slider triangle, you can see
04:51that we have far less clipping going on inside the image.
04:54All right, I am going to go ahead and release the mouse button.
04:57Just to burn in this information if you will, I am going to show you these three
05:01modes against a different background.
05:03I am going to collapse the Adjustments panel, so we have a little more room to
05:05work, click on the Model layer to make it active and then switch that layer
05:08back to Multiply and by pressing Shift +Alt+M or Shift+Option+M on the Mac,
05:12restore the Fill value to 100% by pressing Shift+0, and now I am going to turn
05:17on the Travertino layer so that we can see the model against this brighter,
05:20smoother, marble background.
05:22So this is the effect of placing her on one transparency, the marble on another,
05:26shining the light through both of them.
05:28If I press Shift++, then we switch to the Color Burn mode, notice that we have
05:32all kinds of intensely saturated color values, a lot of color noise going on as a result.
05:38And then finally, if I press Shift++ again, I switch to Linear Burn, and we get
05:43some very dark shadow details, some clipping going on as well, but we are
05:47retaining more of the detail inside the face.
05:50So here's my advice, if you want to darken one image against another, and
05:53there's all kinds of reasons to do so, start with Multiply, that you are when in
05:57doubt darkening mode.
05:59If that's not working for you, if that doesn't have enough impact, then go ahead
06:03and switch for Multiply to Linear Burn and see what that looks like.
06:06If you end up liking the effect, be sure to throw on a Levels Adjustment layer,
06:10and then press the Alt key or the Option key of the Mac and click and hold on
06:13that black slider triangle, just to get a sense of where the clipping is
06:17occurring inside the image.
06:19And that folks is how the major Darken Mode's Multiply, Color Burn and Linear
06:23Burn work here inside Photoshop.

Cleaning up scanned line art
00:00Over the next couple of exercises we are going to take a look at one of the
00:03most common ways for designers in particular to use the Multiply Blend mode and
00:08that's to composite a piece of Scan Line Art against the photographic background.
00:12So image we have this client and this is the only version of the logo that they
00:18can provide us with, they've lost the digital original and this was the only
00:22thing they could find, this laser printed version of it that's got stuff
00:25scrawled on it and has been wadded up and so forth.
00:28And believe it or not this is a pretty common scenario, and we want to take the
00:32thing, clean it up, make it look absolutely beautiful, which we will.
00:36And composite it against this awesome corporate photograph;
00:40and so the two really need to go together, that logo needs to look this good.
00:45And that is something that you can do in Photoshop.
00:47So the first step is to clean up the logo, and this is a necessary first step
00:51when you're working with any Scan Line Art regardless of its quality.
00:54The name of this file is Scanned logo.tif, it's found inside the 04_darken folder.
00:59And the first thing that we need to do is make the blacks as black as possible,
01:03and make the whites as white as possible.
01:05So go up to the Image menu, choose the Adjustments command, and choose Levels or
01:10press Ctrl+L or Command+L on the Mac, and you may ask why we are applying a
01:14static color modification instead of an Adjustment layer, and the reason is we
01:18are working with pretty bad stuff in the first place, and an adjustment layer
01:21isn't going to do us any good in the long run.
01:23All right, so notice these big humps in the histogram, those represent the
01:27colors that ought to be black right here, and then these guys are the
01:31colors that ought to be white, so this is a paper white over here on the right-hand side.
01:35I am going to go ahead and Alt+Drag or Option+Drag this white slider triangle
01:39over to the left side of that big hump on the right, until I see just about
01:44all of that background turn white, and then I am going to back off just a little bit.
01:49So my final Y point value is 170, and that will go ahead and clip
01:53everything that has a luminance level of 170 or brighter, to white, which
01:58is absolutely great.
01:59Then I will press the Alt key or the Option key once again and drag the black
02:03slider over to the right until everything that I think needs to be black, turns
02:08black, and at about 40 that looks pretty good to me.
02:11So black point value 40, a white point value of 170, that will by the way take
02:16everything with a luminance level off 40 or darker inside the original image
02:20and send it to black.
02:22All right, now I'll click OK in order to apply that modification.
02:25Now let's go ahead and zoom in.
02:27We need to get a sense of where the remaining sort of dust and scratches and
02:32what I call snivels, just little bits and pieces of gook are inside of this
02:37image, so we can clean them up.
02:38And you can do that using a Threshold Adjustment layer.
02:42Go ahead and press the Alt key or the Option key on a Mac, click the black-white
02:45icon at the bottom of the Layers panel, and choose the Threshold command, it's
02:49near the bottom, and I am going to call this thing dust finder, and click OK.
02:53And now I will go ahead and crank that Threshold level value all the way up to 255.
02:58So what I'm saying is unless it's absolutely white, unless the pixel in the
03:02image is absolutely white, it's going to appear black, thanks to this
03:06Threshold Adjustment.
03:07Now you can click on the background layer and get rid of all the stuff that's
03:11appearing black that you don't want to have black.
03:14So let's go ahead and zoom in even closer, I'm looking at the image at 200% and
03:19I am going to switch over to my Eraser tool, which you can get by pressing the E key.
03:24And I am going to change the mode, by default it's Brush, change it to Block,
03:28and the Block eraser is this little square that is always nice and sharp,
03:33it's not going to introduce any anti- aliasing or softness or anything along those lines.
03:38Make sure your background color is white, as it is in my case.
03:41And then go ahead and paint away that stuff near the letters.
03:44Now you don't want paint on the letters, by the way like that, right
03:47there, that's a mistake.
03:48I will press Ctrl+Z or Command+Z on the Mac to undo that mistake.
03:52And just go ahead and paint away the most obvious stuff you can get really
03:56close in between the letters like so, for example, I can click here between u and the n and the.
04:01And then I could Shift+Click right about there in order to erase in a straight line.
04:06But it's not actually necessary that you get rid of every single snivel inside the image.
04:11It's okay if you leave a few behind, but you want to get rid of as much as
04:15possible here, and if you feel like you need to work more quickly, by the way
04:19notice, you can zoom out from the image like so, really far in fact, and your
04:24cursor stays the same size relative to the screen, but it's much larger,
04:28relative to the image and that allows me to paint big huge swaths away like so,
04:33if I want to, that's one way to get rid of them anyway.
04:36I could also select them with a Lasso tool and get rid of them that way.
04:39So I will go ahead and paint these things away, the problem with being this far
04:43away from the image is that, of course, you can't really see the very tiny
04:47problems, anyway, so I will go ahead and zoom back in, so that I can see
04:50everything that there is, and I'm once again looking at the image at 200%, I
04:53will go ahead and click inside the a, to get rid of that little thing, paint
04:58below the a, paint between the a and the out like so, paint above the f, there
05:02is some stuff going on above the k, between the i and the k as well down here
05:06below, your results will vary depending on how you're working.
05:10Just give it some patients of course;
05:12you have to get rid of as much as possible after all.
05:15And that looks pretty good, there is that little guy over there on the
05:18left-hand side and otherwise I think, I've done a pretty good job of it, it looks all right.
05:24Okay, now we need to figure out what ought to be absolutely black, because if
05:29you turn off that dust finder a layer for a moment.
05:31You can see that we are missing some details inside the k and inside of some of
05:37the other letters as well, for example, inside the u because that's where the
05:40creases occurred when this piece of paper got folded.
05:43So go ahead and turn that dust finder layer back on double-click on it in order
05:47to bring up the Adjustments panel and crank the Threshold level value down to 1
05:51this time, all the way the other direction, and now you can see what ought to be
05:56black very easily, then click on the Background layer to make it active again,
06:00press the X key to swap your foreground and background colors.
06:03So the background color is black and then paint in black using the eraser.
06:08And notice that we've got some problems down here at the bottom of the n, those
06:12need to be painted away like so.
06:15And it looks like I still have some problems here and there around that g possibly.
06:20So I will press X key in order to paint those guys away, like so, and then press
06:25the X again in order to once again paint with black, because the eraser tool
06:29always paints with the background color.
06:31Paint in the f a little bit, we've got some major problems inside the k region right here.
06:37And down to the bottom of the k as well, paint that guy away, paint this guy in,
06:43and otherwise, I think this looks pretty good, it looks like we have a problem
06:47towards the top of the a.
06:48Again, you are just trying to do your best way this is concerned, you don't need
06:52to micromanage things too much, so it doesn't have to be perfect, because a lot
06:56of these problems will ultimately get reconciled away, although, I am seeing
07:00right here a detail that I want to fix.
07:03All right that looks pretty good to me.
07:04I am going to go ahead and press Ctrl+0 and Command+0 on the Mac, to zoom on out.
07:08And then you can grab that Threshold layer and just press the Backspace key or
07:12the Delete key on Mac to get rid of it, because we are done with it, it was
07:15just a measurement tool.
07:17All right, so we've got a cleaned up logo, it's crooked still, which is a little
07:21bit of a problem, and we need to figure out a way to introduce it into the
07:25photograph, and I'll show you exactly how that works in the next exercise.

Comping line art against a photo
00:00Alright, now that we have managed to clean up our Line Art, how do we go about
00:03introducing it seamlessly into a photographic composition?
00:07Well, that's a question I'll answer by demonstration in this exercise.
00:10If you're working along with me, make sure that you have two files open, one is
00:13called Cleaned-up logo.tif and the other is Company candid.jpg.
00:17We will switch back to the former;
00:19let's introduce it into the photograph by right-clicking anywhere inside the
00:23image window and choosing Duplicate layer, and then change the document from
00:28Cleanedup-logo to Company candid.jpeg.
00:30And I am going to call this new layer logo and click OK.
00:33All right, now let's switch over to the Image file.
00:36We have this whopping big graphic, obviously we need to rotate and scale it.
00:40And we are going to do so using a smart object, because that way we will apply a
00:44nondestructive transformation, and we will always have access to the original
00:48version of the scanned logo, just in case we need to transform it further.
00:52So with the logo layer selected, go up to the Layer's panel fly-out menu and
00:56choose Convert to Smart Object or if you loaded DekeKeys, press Ctrl+Comma,
00:59Command+Comma on the Mac, and now we've got our smart object, so we can
01:03transform this layer as much as we want, without any worries about harming it.
01:08I am going to zoom on in to 100%, so that I can see this image up close, and I
01:13will press Ctrl+R or Command+R on the Mac to bring up my rulers, and I am going
01:17to drag down a horizontal guide, and that will help me decide exactly where the
01:21mean horizontal is, so that I can properly rotate this graphic.
01:24And then, I'll go up to the Edit menu and choose Free Transform or press Ctrl+T
01:29or Command+T on the Mac.
01:31And I actually need to scroll this image up a little bit, so that I can move my
01:35cursor outside the transformation boundary and drag in order to rotate this logo in to place.
01:41And I will scoot it down as well;
01:42I am pressing the down arrow key a few times in order to nudge that logo downward.
01:46And it looks like I have M more or less in place;
01:48that is the base of the M is aligned to the guideline, however the letters drift
01:53down a little bit over here on the right-hand side.
01:55Now just so that I can really gauge what's going on, I am going to drag down
01:59another horizontal guide that aligns to the top of the M like so, and then I am
02:03going to grab that target right there, which represents the transformation
02:07origin, and I am going to drag it down to the bottom left corner of the M, so
02:12that will become my axis of rotation.
02:14All right, now I am going to scroll over little bit, move my cursor outside the
02:18transformation boundary and drag up just a little bit like so, and right at an
02:22angle of about -7.35?, we get the proper alignment.
02:28All right, now I am going to press the Enter key or Return key on a Mac in order
02:31to apply that modification.
02:33Now I still need to scale the logo as well.
02:36Were this not a smart object, turning around and then scaling after I'd rotated
02:41the image, would amount to a destructive modification, but thanks to the fact
02:45that I am working with a smart object, all I have to do to scale the logo, is go
02:49back to the Edit menu, choose Free Transform, and then I am going to press the
02:52Shift key while dragging the corner handle in order to reduce the size of the
02:57image proportionally.
02:58All right, I am going to go ahead and zoom out so I can better see what I'm doing.
03:00And I am going to drag this logo up, and I ultimately decide to scale the logo to 32%.
03:04So I will click on the Chain icon to link the width and height values, and then
03:09I will change either one to 32% like so, and press the Enter key a couple times
03:13in order accept that change.
03:15All right, we no longer need the ruler, so I will press Ctrl+R or Command+R on
03:18the Mac to get rid of them.
03:20We don't need the guides anymore either;
03:21they were just there to help us rotate the logo.
03:24So you can go up to the View menu and choose Clear Guides to get rid of them.
03:27And finally, somehow we have to composite this logo against the
03:33photograph, obviously, we still have that white paper in the background
03:36and that's a problem.
03:37Now you might reasonably think that what you have to do is somehow mask this
03:41logo, which would be kind of a pain in the neck, because not only do you have
03:45the blacks and whites, but you got a lot of grays that are left over from the
03:48half toning and this thing looks ratty enough up close, we don't need to make it
03:52any worse, but turns out, you don't.
03:55The great thing about Blend Modes is that there is always a blend mode to knock
04:00out one of three luminance levels, you can always knock out white, you can
04:04always knock out black, and you can always knockout medium gray.
04:08The Darken modes always knockout white, the Lighten modes always knockout black,
04:13and the Contrast modes, always knockout gray.
04:16So what we are going to do, because we want a knock out white, we are going to
04:19apply a Darken mode and the best of the darkening modes, the when in doubt mode
04:23is Multiply, and notice it does the trick, just like that, we completely get rid
04:28of those whites, we keep every single one of the blacks, we also merge all the
04:33gray values into the background.
04:35It's a miracle where this kind of work is concerned.
04:37Okay, I will press Ctrl+0, Command+0 on a Mac to zoom on out.
04:41Now I will go ahead and position this guy where I want it to be by Ctrl+Dragging
04:44or Command+Dragging the layer, and that looks pretty good to me.
04:47Now it's not perfect, if you zoom on in, you will see that we do have a few
04:52ratty edges, but given that we started with this in the first place, I think
04:57that the result looks pretty fantastic, and you might imagine, if you
05:00started with better Line Art in the first place, you are going to get even
05:03more impeccable results.
05:06And that's how you burn Line Art into a photographic background using
05:10the Multiply Mode.

Colorizing comped line art
00:00All right, now let's say I am so darn proud of this composition, that I want to
00:04go ahead and add a digital signature.
00:06And not only do I want to take that signature which itself is another piece of
00:10line art and merge it against the composition, which is of course just a matter
00:15of applying the Multiply mode, but I also want to assign it some color.
00:19So I want to colorize the signature after the fact, which presents a little bit
00:23of a problem as you will see.
00:24So have saved my progress as, Logo on group.psd found inside the 04_darken folder.
00:30I also have opened this file called Deke sig.tif found inside the same folder of
00:35course, and that this is not my legal signature by the way.
00:40So what I would like you do with it is right-click anywhere inside the image
00:43window and once again, choose Duplicate layer, and let's go ahead and change the
00:48document to Logo on group in this case.
00:51And I will call this new layer signature and then click OK.
00:55And now I will switch back to my composition and there is the image on a new layer.
01:00I am going to Ctrl+Drag or Command+Drag it down to the lower right-hand corner
01:04and zoom in on the signature as well.
01:06Now obviously we need to drop out the white keep the black, all you need to do
01:10there is press Shif+Alt+M or Shift+ Option+M on the Mac in order to drop out
01:14those whites and merge those grays exactly in the place.
01:18I really want to drive this point home that you never have anything, but
01:22absolute darkening where Multiply is concerned.
01:25So it really is as if you took this photograph and actually signed it, the
01:30difference being of course that you didn't harm the original photograph, and you
01:33can create one signature and place that on as many different images as you want.
01:38All right, I am going to zoom out just a little bit here.
01:40And now let's say at this point I want to give the signature a little bit of
01:44blue in order to sort of match this guy's shirt.
01:47And I will do that by dropping down to the fx icon and choosing Color
01:52Overlay, and that's going to initially change the entire layer to red as you can see here.
01:57First thing we need to do is style in a different color.
01:59So click on the color swatch to bring up the color picker dialog box and
02:03then you can click somewhere inside the image window in order to lift the sample blue.
02:08And in my case, I am going to change this Hue value to 215 let's say, crank the
02:12Saturation value up a 100, and take the Brightness value down to 25%.
02:18So we have a nice rich blue to work with, click OK.
02:20All right, how we merge that blue into the signature, well, you can go ahead and
02:27try the Multiply mode if you want to just to get a sense of what's going on, but
02:30that's exactly the opposite of the effect that we are looking for.
02:34We are burning the blue into the signature, so as a result the signature gets
02:37even darker and now we are seeing the paper which was initially white, turned
02:41dark blue, and we can of course see the edges of our Line Art.
02:45What we want is the opposite effect, and we are going to be discussing this
02:49Blend Mode in lots of detail in the very next chapter, however, the opposite
02:54of Multiply is green.
02:56If you're struggling to try to figure out exactly which blend mode to work with,
03:00and you're not sure if you need to darken or lighten or what you need to do,
03:03starting with Multiply is never a bad idea.
03:06If there is a blend mode, that is the most useful blend mode in
03:08Photoshop, that's it.
03:10And then, of course, if you discover, gosh!
03:12I want the opposite effect, then just go ahead and switch to Screen;
03:16Screen is the opposite of Multiply.
03:18And notice as soon as I apply the Screen Mode, I end up brightening the
03:23letters as you can see.
03:24So instead of black as they were before, I'll turn off Color Overlay just for a
03:28moment, so you can see the difference.
03:29There are the black lines and these are the lighter blue lines, they are
03:34still very dark of course, they look as if perhaps they were drawn with a ballpoint pen.
03:37But if you zoom in, which you can do when the Layer Style dialog box is open by
03:43Ctrl+Clicking or Command+Clicking on the Mac, you'll see that we've got a little
03:47bit of an edge going on right there around the perimeter of the layer, and
03:52what's happening here is, we're applying this Blend Mode the Screen Mode with
03:56its blue, after we've gotten done applying Multiply.
04:01So as a result, we are using the blue to lighten the guy's shirt and that is not what we want.
04:06Here is how you solve this problem;
04:08you click on Blending Options right there in order to switch to the Advanced
04:12Blend Settings here inside this dialog box, which we will be discussing in more
04:16detail in a future chapter.
04:18And here's the guy we are looking for, the very first checkbox notice that it
04:21says Blend Interior Effects as Group.
04:24What that means is we'll take a Color Overlay effect, we will blend it first
04:28into the Line Art, which will lighten the signature and it will do nothing to
04:32the background, because Screen is a brightening mode, it cannot do anything to white.
04:37Then we'll go ahead and apply the Multiply Blend mode to the entire composite layer.
04:43And all you have to do to make that happen is turn on this checkbox, watch what
04:46happens to the perimeter, that area of bright blue right there.
04:49As soon as I turned the checkbox on, it absolutely goes away.
04:52So that's all there is to that, then click OK in order to accept that modification.
04:57All right, I am going to press Ctrl+0 or Command+0 on a Mac in order to zoom on
05:01out, and that for instance is how you introduce and colorize a piece of Line Art
05:06against the photographic background, using a combination of Multiply and Screen
05:11working together, here inside Photoshop.

Masking with a darken mode
00:00All right, now let's see a compositional application of a Darken Blend Mode.
00:04We are going to take this last version of the model, Linear Burned against the
00:07marble background and we're going to mask her, so that she doesn't have any of
00:11that marble texture running through her face or skin tones, and it's an easy
00:16mask to create, thanks to the fact that we have an underlying layer of
00:19darkening to work with. All right!
00:21I have saved this version of the image as Linear burn.psd, found inside the
00:2504_darken folder, and I am going to go ahead and turn off that Levels
00:29adjustment layer for now, we'll come back to it and then click on the model
00:32layer in order to select it, and I'll press Ctrl+J or Command+J on the Mac in
00:36order to jump it to a new layer.
00:38And I'll go ahead and return this layer to the Normal Blend Mode by pressing
00:41Shift+Alt+N or Shift+Option+N on the Mac.
00:44Now we need to mask away the background, it's a flat light background.
00:48So it's pretty easy to do, by going up to the Select menu and choosing the Color
00:50Range command or if you loaded DekeKeys, you can press Ctrl+Shift+Alt+O or
00:51Command+Shift+Option+O on the Mac.
00:52Now I'm going to click in the background and Shift+drag around in various
00:53locations in the background, just to make sure I have the entire thing selected.
01:18A Fuzziness value of 40 is just fine.
01:19I'm assuming that your Invert checkbox is turned off.
01:20Then go ahead and click OK to select that background.
01:21We are selecting into the skin as well, that's okay.
01:22All right, now let's apply that selection as a mask by dropping down to the Add
01:23Layer Mask icon at the bottom of the panel and Alt+Clicking or Option+Clicking
01:26on it, and I pressed Alt or Option, because I want to mask away the background,
01:29as opposed to keeping it.
01:31Now notice that I've masked away her forehead and parts of the left hand side of
01:35her face and neck as well.
01:37That's a problem that we can address very easily by Alt+Clicking or
01:40Option+Clicking on the Layer Mask thumbnail, so we can see the mask
01:43independently of the rest of the image.
01:45Then I am going to switch to the Brush Tool, which you can get by pressing the B key.
01:48I'll right click inside the Image window in order to bring up the Brush panel.
01:53Notice that my Size value is set to 250 pixels, that doesn't really matter that
01:56much, what does matter is that the Hardness is set to 0%, that's what we want.
02:01So I'll go ahead and press the Enter key or the Return key on the Mac in
02:04order to accept that.
02:05I need to make sure that my foreground color is set to white, which it is and
02:08I'll change the Mode from Normal to Overlay, because we're going to be doing
02:13that overlay paining trick that allows us to paint away the whites, while at the
02:17same time protecting the blacks.
02:18All right, now I'll paint inside of the mask like so, and down here around the
02:24neck as well and into the shoulders in order to tighten up those edges.
02:28All right, now I need to paint away the stuff inside of her face and down
02:31here along her neck.
02:32So I'll switch back to the Normal mode just by pressing Shift+Alt+N or
02:36Shift+Option+N on the Mac and because the Brush Tool is selected, that changes
02:40the mode for the brush as opposed to the layer.
02:43Then I need to right click inside the Image window and crank the Hardness value
02:46up 100%, and I'll paint away these areas like so, and so, I don't want to paint
02:52next to the edge, just near it, in order to get rid of all those details.
02:56All right, now I need to firm up the blacks in the background, so I'll
02:59right-click in the Image window and restore the Hardness to 0% and press the
03:04Enter key a couple of times, the Return key a couple of times on the Mac, press
03:07the X key in order to change the foreground color to black, and then I need to
03:12change the Mode back to Overlay, which you can do by pressing Shift+Alt+O or
03:17Shift+Option+O on the Mac.
03:19And again, because the Brush Tool is active, that changes the mode for the
03:22brush, not the layer.
03:24Now I'll go ahead and paint along the sides of the hair and the neck and down
03:27here along the shoulder region.
03:29We've got some areas over on this side that need to be painted to black as well,
03:33and that finishes off our mask.
03:35It's pretty much that easily done.
03:37Go ahead and Alt+Click or Option+Click on the Layer Mask thumbnail in order to
03:41return to the full color composite image.
03:43All right, now at this point, it looks like we have some pretty brutal
03:46transitions around the left side of the hair, as well as the right side of the
03:50hair, her ear is too bright, and so we need to mask some of those details away,
03:55and I'll show you how that masking works in the next exercise.
Collapse this transcript
Refining a mask with Multiply
00:00All right, now at this point we have a pretty good mask, but it's not sensational.
00:05We do have some brittle details around the edges here.
00:08I'm not altogether convinced that she really belongs against this marble background.
00:12So what we're going to do is darken up some of the edges and we can't do that
00:16because we have this dark version of the model right here in the background, and
00:21as a result we can adjust our mask to reveal portions of that darkened image.
00:26And as you'll see this adjustment once again relies on a darkened mode.
00:30I've saved my progress as Base mask.psd, it's found inside the 04_darken folder.
00:35And what we're going to do is blur the mask inward.
00:38We're going to make sure it blurs inward only, thanks to the Multiply mode.
00:43But before we go changing our mask because this will be a destructive
00:46modification at least in so far as the mask is concerned, I suggest we save it
00:51out as an alpha channel.
00:52So switch over to the Channels panel and grab that layer mask right there and
00:56drag it onto the little page icon at the bottom of the panel to make a copy of
01:00it and then let's go ahead and name this copy original and now we've got it
01:04saved, so we can always come back to, if we need to.
01:07All right, now switch back to the RGB image once again, switch to the
01:11Layers panel as well, and then click on the layer mask thumbnail to make
01:14sure it's selected.
01:15Go up to the Filter menu and choose Blur and then choose Gaussian Blur, and I'm
01:20going to apply a big helping of blur and we can get a sense of what's going on
01:24by clicking along one of the edges here.
01:27And notice that I've taken the Radius value up to 20 pixels, and I can see the
01:31results of that radius here inside the dialog box.
01:34I'll go ahead and click OK in order to accept that change.
01:37Now notice, if you zoom-in here, you can see that the blur is going both directions.
01:42It's not only blurring into the model, it's also blurring outward, and as a
01:46result, she has the effect of a kind of a halo, surrounding every portion of her
01:50face and hair and so forth.
01:52So to eliminate that halo, you go up to the Edit menu and you choose Fade
01:56Gaussian Blur or you can press that keyboard shortcut Ctrl+Shift+F,
02:00Command+Shift+F on the Mac and let's go ahead and switch the blend mode
02:04from Normal to Multiply.
02:07So we're switching the mode applied to that blur after the fact, and notice now
02:11that we've lost the halo, but we're keeping the blur, it's just that it
02:15exclusively extends inward.
02:17Now click OK in order to accept that change.
02:20All right, now let's go ahead and zoom back out by pressing Ctrl+0 or
02:24Command+0 on the Mac.
02:25Few more modifications need to be made.
02:27Her ear is still a little bit bright it seems to me and we still have a little
02:30bit of brightness around her hair.
02:32So I'm going to scroll down just a little bit, so that I can see the top of the
02:36image, and I'm going to switch over to my Brush Tool once again.
02:39And I'm going to right-click inside the image window, just to confirm that the
02:42Hardness is set to 0%, which it is.
02:45I want you to restore the Mode back to Normal by pressing Shift+Alt+N or
02:49Shift+Option+N on the Mac.
02:51We're just going to hand paint some of the mask away with a fuzzy brush, which
02:55is not normally something I recommend you do, if you are trying to create a
02:58precise mask, but in this case because we have that Linear Burn version of the
03:03model in the background, we've got a lot of latitude.
03:05So I'll go ahead and turn that model layer back on, make sure the layer mask is
03:08selected as it is, increase the size of my brush by pressing the right bracket key
03:13 [ a couple of times, and then just spot click here and there around the left side of the hair in order to paint it dark, like so.]
03:13And then I'll do the same thing over here on the right side of the hair and into
03:24the ear as well, in order to paint some of those details away and reveal the
03:29dark version of the model in the background.
03:31Now I've probably gone too far.
03:33As you can see here, it looks like she's got a scratch on her right cheek and
03:37what that is, if I turn that model layer off, that's a bit of the marble
03:41showing through her flesh.
03:43So I need to mask that detail back in, by turning that layer back on, reducing
03:47the size of my brush by pressing the left bracket key
03:53 [, switching the mode back to Overlay by pressing Shift+Alt+O or Shift+Option+O on the Mac, changing the foreground color to white, by pressing the X key, and then I'll go ahead and paint inside that cheek and you can see that that scratch or whatever it might end up looking like, disappears.] All right!
03:53Let's go ahead and zoom back out in order to take in the image.
04:09Now if we didn't have that dark model in the background, notice, if I turn that
04:13layer off we're seeing all kinds of problems with the mask.
04:17The mask is not anything to write home about.
04:19However, that's okay.
04:21As long as the composition looks good that's all that really matters, but we do
04:24have a little bit of a problem there.
04:26It looks like I've got little bit of marble coming into her ear.
04:29So I'm going to click to try to paint some of that away, maybe some of this
04:32stuff up here as well. All right!
04:34Press Ctrl+0, Command+0 on the Mac to zoom-out.
04:37Now the final step is to make her look more at home in her background.
04:40So I'm going to go ahead and press the M key to switch back to my Rectangular
04:43Marquee Tool and I'm going to turn on that adjustment layer.
04:46Notice, it's not doing anything right now, because I didn't make any
04:49modifications to the adjustment.
04:51I'm going to rename the layer however deepen, and I'm also going to press the
04:55Alt key or the Option key on the Mac and click that horizontal line between
04:59those two layers in order to clip the adjustment inside of the model.
05:03And then I'm going to change the blend mode assigned to the adjustment to none
05:08other than Multiply, in order to go ahead and multiply her into herself.
05:13So even though the adjustment is entirely empty, we are creating a much darker
05:16version of the model, that's too dark however.
05:19So I'll press the Esc key to deactivate the blend mode and I'll press the 5
05:23key to reduce the Opacity value to 50% and that is the final version of the masked model.
05:29It goes lickety-split, thanks to the fact that we're masking on top of a
05:33darkening layer here inside Photoshop.

5. The Lighten Modes
Lighten vs. Lighter Color
00:00In this exercise we're going to take a look at the two simplest Lighten modes,
00:04which are Lighten and Lighter Color.
00:06Currently I have the night layer turned on here inside the Layers panel, I'm
00:10also going to turn on the hoody layer and click on it.
00:13Now notice that this image is set against the black background, but the
00:16background doesn't extend all the way to the left-hand side.
00:20If I go ahead and grab my Magic Wand Tool just so I can task what's going
00:24on inside this layer.
00:25And then I set my Tolerance value to 0, Anti-alias is turned off, and Contiguous
00:29is turned on, then I'll click inside the background to the left of this fellow's
00:33hood and you can see that I'm selecting the entire background which tells me it
00:37is one continuous color.
00:39If I press the I key to switch to the eyedropper and then click inside that
00:43area, the color panel is telling me that this is absolute black, which means
00:48that if I apply a Lighten mode to this layer, any of the five lighten modes in
00:52fact, then this background is going to entirely disappear.
00:56So I'll go ahead and press Ctrl+D, Command+D on the Mac to deselect the image.
01:01And now I'm going to change the Blend Mode from Normal to Lighten, and you can
01:04see that in fact that background entirely disappears and the significance is
01:09that we don't have any edge along the left-hand side of this layer.
01:12All right, now as you may recall from my discussion of darken versus darker
01:15color, the difference is that darken for example is applied on a
01:20channel-by-channel basis, but darker color is applied to the composite image.
01:25The same is true of lighten versus lighter color.
01:28So in a case of lighten we're seeing Photoshop keep the pixel in the active
01:32layer if it's lighter than the pixel behind it on a channel-by-channel basis,
01:37which means that we end up achieving a little bit of a transition here inside
01:41the composite full-color preview.
01:42But again if you were to go to the Channels panel and check things out then you
01:46would see that we have some stark transitions in the Red channel, equally stark
01:50transitions in the Green channel, and stark transitions in the Blue channel.
01:54The reason they end up reconciling fairly smoothly in a composite is because
01:59those transitions are different in each and every one of the channels.
02:03Compare that to, if I were to switch back to the Layers panel and change the
02:06Mode from Lighten to Lighter Color.
02:09In this case we end up with some very sharp transitions, either a pixel is on
02:15or it's off, because the blend mode is applied in exactly the same way to each and every channel.
02:21So that's how Lighten and Lighter Color work.
02:24In the next exercise, I'll show you how to use the Lighten mode to achieve
02:27a filtering effect.

Creating filter effects with Lighten
00:00In this exercise I'll show you how to use the Lighten mode to achieve a quick
00:03and dirty filtering effect.
00:05I've restored the saved version of Lighten demo.psd.
00:09Let me go ahead and turn on the gang layer here and click on it to make it active.
00:13And then because we want to apply some smart filters, let's convert it to a
00:17smart object, by going up to Layers panel fly-out menu and choosing Convert to
00:21Smart Object or if you loaded my DekeKeys shortcuts, you can press Ctrl+,.
00:25Next I'm going to go on to the Filter menu, choose the Sharpen command and then
00:29choose Smart Sharpen.
00:31And I'm going to apply something of an over-the-top effect here.
00:34I've cranked the Amount value as you can see up to 500%, and I've taken the
00:38Radius value up to 10 pixels and set the Remove option to Lens Blur.
00:43More Accurate is turned off;
00:45I'll go ahead and click the OK button in order to apply that filter.
00:49Now let's modify the Blend settings by double-clicking on the little slider icon
00:52over here to the right-hand side of the word Smart Sharpen.
00:56And I'm going to switch the Mode from Normal to Lighten so that we're keeping
00:59the sharpening effect exclusively where it's brighter than the original image.
01:04Now I'm going to take the Opacity value down to 25% in order to settle that
01:09effect down, so that we don't have too much in the way of blown highlights.
01:13Now I'll click OK in order to accept that effect, and just to give you a sense
01:16of what's going on here, I'm going to zoom in on the image so that we're seeing
01:20it at the 100% view size.
01:22And I'll turn off this Smart Sharpen filter, so that's the appearance of
01:25the original image.
01:27If I were to press Ctrl+Z or Command+Z on the Mac, now we'll turn the filter
01:31back on and you can see what the image looks like now.
01:33All right, I'm going to get rid of that Filter Mask by right clicking on it and
01:37choosing Delete Filter Mask.
01:38Now let's turn these guys into kind of ghost gangsters if you will, by going up
01:44to the Filter menu, choosing Blur, and then choosing Gaussian Blur.
01:48Now I'm going to crank the Radius value up to 20 pixels, we're just going to
01:52blur the heck out of these guys and then click OK.
01:56And now as you might predict, I'll go ahead and double-click on the slider icon
01:59to bring up the Blending Options dialog box and I'll change the Mode once again
02:03from Normal to Lighten, so we end up getting the ghosting effect you see here. Now I'll click OK.
02:09Now I feel like the effect is a little tight, in other words it's filling in a
02:13lot of the shadow details inside of these gentlemen's faces.
02:16So I'm going to double-click on the words Gaussian Blur to revisit the Gaussian
02:20Blur dialog box, and I'm going to crank the Radius value up to 66 pixels and
02:26then click OK in order to accept that effect.
02:29And now we have the ghost gangsters, once again, if I click on the eyeball in
02:33front of the Smart Filters then we'll see the original version of this layer.
02:37If I turn the Smart Filters back on, then we can see the ghosting effect
02:41achieved, as I say very simply, using a couple of filters and the Lighten blend mode.

The Screen and Dodge modes
00:00In this exercise we'll take a look at the more robust lightning modes which
00:04include screen which is your Go To mode where lightning is concerned as well as
00:09the two Dodge modes, Color Dodge and Linear Dodge add.
00:13And I'm going to go ahead and zoom in on the image so that we can see it at
00:16the 100% view size.
00:18And I'll switch the Blend Mode from Normal to the first of the light modes,
00:22Lighten, and you can see that we end up keeping the lightest pixel on a
00:26channel-by-channel basis which ends up creating some fairly harsh transitions in a few spots.
00:32So some of the pixels end up remaining entirely opaque, other pixels drop away
00:37entirely to transparency and then there's a variety of pixels that get along
00:42differently on a channel-by-channel basis.
00:44Compare that to what happens when we switch to the Screen Mode, which I'm
00:48going to do by pressing Shift+Plus, because Shift+Plus always advances to the
00:52next mode in the list.
00:53And notice that now we get a uniform brightening mode, we're not left with
00:57any harsh transitions.
00:59The only color that drops out entirely is the black of the background;
01:03otherwise even very dark colors brighten with white brightening absolutely.
01:08Now because of the underlying math associated with screen, you don't end up
01:12getting any clipping.
01:13Nothing clips to white in other words, unless it was already clipped to white in
01:17one of the blended layers.
01:19And in our case what that means is we create this nice uniform ghosting effect.
01:24I'm going to zoom back out by pressing Ctrl+0 or Command+0 on the Mac, and
01:29for the moment I'm going to turn off that gang layer and click on the night layer down below.
01:33And notice if I turn that layer off there is another layer below it, this
01:37texture layer, and by the way, I should say, all these photographs come from the
01:41Fotolia Image Library.
01:42All right, let's say we want to create an interaction between these two layers,
01:46I'm going to go ahead and click the night layer to turn it on and I'll switch to
01:49the Screen Mode, this time by using a shortcut, which is Shift+Alt+S or
01:54Shift+Option+S on the Mac, and you can see that we end up with this wonderful
01:58blend between these two very dark layers.
02:00None of the luminance levels entirely clip by the way, so the reason this moon
02:04is so bright is because it was already very bright in the first place, but we do
02:09have differences between the neighboring pixels.
02:11Well, let's compare that to what happens if I switch to one of the Dodge modes,
02:15and I'll do so by pressing Shift+Plus once again, which in this case takes me to
02:20the Color Dodge mode.
02:21Notice now some of the luminance levels actually settle down, some of the
02:25intermediate colors for example.
02:26However, we do end up with some clipping inside of that moon, and it's
02:31very pronounced as well.
02:33So we have these hyper saturated colors with big huge transitions
02:37between neighboring pixels.
02:38All right, I'll go ahead and zoom out again, so we can take in the
02:41entire composition.
02:43It's an interesting effect;
02:44I have to say, I will also say however that I do not use Color Dodge on anything
02:49resembling a regular basis.
02:51Every once in a while I can prove to be somewhat interesting, and because it's a
02:55member of the Fill Opacity 8, I can press let's say Shift+8 in order to reduce
03:00that Fill Opacity to 80%, which results in this extremely subtle effect here.
03:05All right, I'm going to boost that Fill Opacity back up by pressing Shift+0.
03:10Now the way I work is I'll start off with screen, see how that looks.
03:16If I'm not satisfied with that effect, if I feel like I need something more,
03:20then I'll switch to the Linear Dodge mode, which appears directly below Color Dodge.
03:25The reason it says (Add) in parenthesis that's actually a recent addition to the
03:30name of that mode, it happened a few versions back.
03:32And the idea is Photoshop is acknowledging the underlying math of the
03:36mode, which is a simple function of adding up the luminance levels,
03:40between the blended layers.
03:42So when I choose (Add), we're going to end up with this more pronounced effect here.
03:46It's a somewhat subtle difference, although it's a big difference from Color
03:49Dodge, here's Color Dodge, just for the sake of comparison, and here's
03:53Linear Dodge once again.
03:55However, do note that we end up with these blown highlights inside of the moon
04:00and inside of some of the details of the clouds.
04:03If you want to settle those highlights back, which I do, then just remember
04:08that Linear Dodge like Color Dodge, and like the two Burn Modes is a member of
04:13the Fill Opacity 8.
04:14So if I press Shift+8, in my case, to reduce the Fill Opacity value to 80%, I
04:19end up regaining the lost highlights across the board.
04:23Now I'm going to go ahead and turn on the gang layer, just so that we have an
04:26interaction between all the layers that we've modified so far.
04:29In the next exercise, I'll show you how to use Linear Dodge to specifically
04:33punch up white text.

Blending white type, darkening shadows
00:00In this exercise I'll show you a great way to create interaction between white
00:04text and the composition using Linear Dodge.
00:07We'll also correct the luminance levels for the entire composition, using Multiply.
00:12Notice here in the Layers panel that I have this layer called Text.
00:15It's actually a text layer that I converted to vector shapes.
00:18I'm going to go ahead and click on that layer to make it active.
00:21Now whenever you're working with white type, it really doesn't matter whether
00:25you have the Normal mode selected or one of the Lighten modes.
00:28Notice, if I switch from Normal to say Screen, the text looks exactly the same
00:33as it ever did, because you can't brighten beyond white inside of Photoshop.
00:38So if it was already white in the first place, it's going to stay white, subject
00:42to any of the lighten modes.
00:44There is an exception however, if you work with the Fill Opacity value.
00:48So let's say I press the Escape key in order to deactivate the Blend Mode here
00:51on the PC, and then I press Shift+5 to reduce the Fill Opacity to 50%.
00:57Notice that I end up with translucent white text.
01:00And it looks no different by the way, if I were to switch back to the Normal
01:04mode, and the reason is because the Screen mode is not part of the Fill
01:08Opacity 8, it doesn't respond any differently to Fill Opacity than it does to Standard Opacity.
01:13But it's not the case however, if you work with one of the Dodge modes.
01:17So if I switch for example to Color Dodge, I'm going to end up with an entirely
01:22different effect at this low opacity value, I'll get an even better effect, if I
01:27press the Escape once again to deactivate the Blend Mode and press Shift+Plus in
01:32order to switch to the Linear Dodge mode.
01:34And notice that we keep the whites in the bright areas of the background and we
01:39end up achieving other colors when the background gets dark, and that to my eye
01:43is exactly the kind of text transition I'm looking for.
01:46Now the problem at this point compositionally anyway is that even though we
01:50started with some very, very dark images in the first place, we've applied
01:55so many helpings of the lighten blend modes that we are starting to lose our intense shadows.
02:00So I'm going to click on this hoody layer at the top of the stack, and then I'm
02:03going to press the Alt key or the Option key on the Mac, click the Black & White
02:07icon at the bottom of the panel and choose Brightness/Contrast.
02:10Now I'm not going to modify the settings of this layer so I'll just call it
02:13dummy and click OK, and then I'll collapse the Adjustments panel, bring back the
02:18Layers panel, and I'm going to darken up the overall composition by pressing
02:22Shift+Alt+M or Shift+Option+M on the Mac to switch to the Multiply mode.
02:27Now even though we're not clipping anything, because once again, Multiply
02:31cannot clip our shadows.
02:32I do feel like we've gone too far with the effect, so I'll press the 5 key in
02:37order to reduce the opacity value to 50%.
02:40And now if I turn the layer off, you can see how bright the composition was just
02:44a moment ago, turn it back on, and that brightness is settled down.
02:48So the moral of the story here is that you can use the when in doubt Darken mode
02:52Multiply, in order to correct for a blended bright image.
02:56In the next exercise, I'll show you how to use the Screen Mode to create a
02:59classic double exposure effect.

Creating a classic double-exposure effect
00:00In this exercise I'll show you how to use the Screen Mode to create a classic
00:04double exposure effect between two dark photographs.
00:07I'm going to turn the dummy layer off, switch to the gang layer and press
00:11Shift+Alt+N or Shift+Option+N on the Mac in order to return to the Normal mode.
00:15And by the way, bear in mind that all these keyboard shortcuts assume that
00:19you have one of the tools other than the second group of Paint and Edit Tool selected.
00:24Now I'm going to turn on the hoody layer and click on it to make it active, and
00:29let's say we want to create a double exposure effect, between this layer and
00:33the gang layer below.
00:34Now we just go ahead and switch to the Screen Mode by pressing Shift+Alt+S or
00:38Shift+Option+S on the Mac.
00:40Problem is of course, we've never assembled a composition like this, with the
00:44hoody guy's face over this hostile middle guy in the background, so we need to
00:48move this layer around.
00:49I'm going to go up to the Edit menu and choose a Free Transform command, or
00:53press Ctrl+T or Command+T on the Mac, then right-click inside the image and
00:57choose the Flip Horizontal command.
01:00And I'm going to go ahead and drag this guy over to the left-hand side of the
01:03composition like so, and right about here it seems appropriate to me.
01:07You can scale him if you want to, you have a little bit of latitude where
01:11this layer is concerned, but I'm not, I'm just going to go ahead and lift him up a little bit.
01:15So part of his eyebrows cut off there at the top, and then press the Enter key
01:19or the Return key on the Mac in order to accept that modification.
01:24It seems to me our larger hoody guy should have a little bit of sharpening
01:27applied to him, so I'm going to convert him to a Smart Object.
01:31By clicking on the Layer panel fly-out menu and choosing the Convert to Smart
01:34Object command and then I want to duplicate the Smart Sharpen filter, and I'll
01:38do so by pressing the Alt key or the Option key on the Mac and dragging just the
01:43words Smart Sharpen and dropping them onto the hoody layer, and that will copy
01:48if I go ahead and expand the layer here.
01:50You'll see that copies the Smart Sharpen filter without copying Gaussian Blur.
01:55And as long as I'm here, I'll right- click inside the Filter Mask and choose
01:58Delete Filter Mask to get rid of it.
02:01We do want to filter this layer just a bit, so if the hood isn't cutting through
02:06this guy's face, they're actually the same guy, but one is very big and one is
02:10small, so we don't want to hurt the small guy.
02:13I'm going to create a layer mask by dropping down to the bottom of the Layers
02:16panel and clicking on Add Layer Mask, and then I'll go ahead and grab my Brush Tool.
02:22If I right-click inside the image window you can see I've set this size to 400
02:25pixels, the hardness is 0%.
02:26I might actually go ahead and crank that Hardness value up to say 50%, I'll
02:31press the Enter key a couple of times in order to hide that panel.
02:34Maybe reduce the size of my cursor a little bit by pressing the left bracket key.
02:38Make sure that your foreground color is black, which it is in my case, and then
02:42click right about there in order to interrupt the hoody a little bit, so it's
02:46not cutting through the smaller guy.
02:48And I might paint down a little bit inside the hoody, up a little bit as well,
02:52in order to achieve this effect.
02:54We definitely need to bring that text back, so we're identifying this group of
02:57people whether they're a band or whatever they are.
03:00So I'm going to grab that text layer and drag it and drop it on the top of the stack.
03:05Now we've got some outlines that are showing up here, that's just because
03:08my Vector Mask is active, so I'll click on the Vector Mask thumbnail to turn it off.
03:12It seems to me that we're losing the legibility of the text, and there is really
03:16no better way to solve that problem.
03:18Then I drop down to the fx icon and choose Drop Shadow, and I'm going to crank
03:22the Opacity value up to 100%.
03:25Not too concerned about the angle, but I'm going to take that size value up to
03:2915 pixels, it'll leave the distance at five pixels, and then click OK in order
03:34to achieve this final composition.
03:37So all right, I'm not sure how often you're going to want to create the classic
03:40possibly cliched double exposure effect, but if you do, you can grab those dark
03:45images and blend them together using the Screen Mode.

Making dark line art bright
00:00In this exercise I'll show you how to take those black and white scanned line
00:04art elements that I showed you how to integrate in the previous chapter and
00:08we'll turn them into bright design elements using the Screen mode.
00:12Over here in the Layers panel I'll click on the signature layer which is my
00:15signature down here in the lower right corner and then I'll Shift+Click on the
00:18logo layer, so they're both selected.
00:20Now I will right-click inside the image window and choose Duplicate Layers.
00:24I'll change the document to Dramatic portrait.psd and then click OK. All right!
00:29Now let's switch over to that file.
00:31Notice that the scanned line art integrates seamlessly into our dark
00:35composition, but wouldn't it be better if the logo and the signature were
00:38bright instead of dark.
00:40So I'm going to start things off by clicking on the signature layer to make it
00:43active and then I'll go up to the Image window, choose Adjustments and choose
00:48the Invert command or I could just press Ctrl+I or Command+I on the Mac, that
00:52will go ahead and invert this layer.
00:54Let's zoom-in on it so we can see what we're doing here.
00:56And now I'm going to reverse the Blend Mode from Multiply to it's opposite,
01:01which is the Screen mode and we end up with this effect here.
01:04Now the Color Overlay effect is for the moment messing things up, so I'm just
01:07going to turn it off.
01:09We'll come back to it in just a moment, but you can see just like that we're
01:12able to turn black on white scanned line art into line art that appears white
01:18seamlessly integrated into a dark composition.
01:21Let's go ahead and zoom-out once again and I'm going to switch to the logo layer.
01:25Now obviously I want to invert it as well, but if I go up to the Image menu and
01:29choose Adjustments then Invert is not available to me.
01:33And the reason is because I converted this logo to a smart object, which was a
01:37good thing however that means it needs a special approach.
01:40So we're going to invert it using an Adjustment layer.
01:43So press and hold the Alt key or the Option key on the Mac, click the
01:46black-white icon at the bottom of the Layers panel and choose Invert and
01:50I'm just going to go ahead and call this layer invert, that part doesn't really matter.
01:54This part does, you need to turn on the checkbox Use Previous Layer to
01:57create Clipping Mask.
01:59So we're affecting the logo layer only. Now I'll click OK.
02:03We don't need to see the Adjustments panel.
02:05In fact, it irritates me like crazy that it appears and takes up so much room
02:09when there are no options for invert.
02:11I'll just go ahead and double-click to the right of the word Masks to collapse
02:14the panel, go ahead and expand the Layers panel now.
02:17Next, click on the logo later to make it active and switch it for Multiply once
02:21again to its opposite Screen and we end up with this bright logo. So far so good.
02:26Let's say now we want to colorize the logo.
02:29In fact I want the logo to be roughly the color of the models eye-shadow.
02:33I think that look awesome.
02:35So I'm going to go ahead and grab the Color Overlay effect that I had applied to
02:39signature and I'm going to drag it and drop it onto the logo layer, which will
02:43move it as opposed to copying it, which because I didn't have the Alt or Option
02:47key down it goes ahead and moves that layer effect instead of copying it, but it
02:51also messes things up.
02:52So I'm going to double-click on Color Overlay, bring up the big Layer
02:56Style dialog box, then click on the color swatch in order to bring up the color picker.
03:00Click inside the bright portion of the eye-shadow in order to lift a
03:04representative color and I'm going to modify my HSB value slightly.
03:08I'm going to change that Hue value 35, I'll also change the Saturation to 35%
03:14and they'll take the Brightness value up to 80% and click OK.
03:18Now that produces exactly the opposite of the effect I'm looking for.
03:22We're colorizing the background behind the scanned line art but we're not
03:26colorizing the letters and that's because we need to shift the blend mode from
03:30Screen, which was previously brightening the letters to Multiply, which will now
03:35darken them, and that will send the color inside those now white layers, which
03:41is exactly what we're looking for but we still need to drop out the background.
03:46And we'll do that the same way we did back in the previous chapter by clicking
03:50on Blending Options and then turning on that top checkbox Blend Interior Effects
03:55as Group and that goes ahead and multiplies the color into the scanned logo art
04:01before applying the Screen blend mode to the overall layer.
04:05And as a result we drop out that excess color. All right!
04:08Now I'll click OK in order to accept the change.
04:11Just the couple of more things I want to do.
04:13I want to make this logo bigger and thanks to the fact that it's a smart object I can.
04:17So I'll go up to the Edit layer and choose the Free Transform command or press
04:21Ctrl+T, Command+T on to Mac and then I'm going to Shift drag this corner handle like so.
04:27I'm looking to scale this logo by 48%, so I'll go ahead and click on the chain
04:31between the W and H values and I'll change the Width values to 48% and as you
04:36can see both values change in kind and then I'll press the Enter key a couple of
04:39times or the Return key a couple of times on the Mac to accept that change.
04:43Just so you can get a sense of how flexible these source of blended compositions are.
04:48I'm going to turn on this magnified layer, which is in increased resolution
04:52detail from that original photograph and I might go ahead and Ctrl+Drag or
04:57Command+Drag the logo over just a little bit as well.
05:00In any case, that friends is how you turn black on white line art into a
05:05bright line art elements that integrate seamlessly into your compositions here inside Photoshop.

Masking with a lighten mode
00:00In this exercise I'll show you one way to create a masked composition with the
00:04help of a Lighten Blend Mode.
00:06Specifically we'll be taking these two layers over here in the Layers Panel.
00:10I got a speculator layer in front with this model against this kind of
00:13grunge wall background.
00:15If I turn it off you can see that we have this 3D data layer in the background.
00:19I want to merge them together in order to create this final effect here.
00:23So it's not only a bright interaction between the two layers but I've gone ahead
00:27and masked the model as well so that he is mostly opaque, not entirely because
00:33we can see some of the lines up here in the shoulders, but he is generally an
00:36opaque image element.
00:37Now the first thing I'm going to do is turn on that speculator layer and jump it
00:42by pressing Ctrl+Alt+J or Command+Option +J on the Mac and I'll call the copy of
00:47the layer normal and click OK.
00:48Now I'm going to turn it off and by the way these layers are currently set to
00:53the Normal Blend Mode.
00:54I'm going to turn that one off.
00:56Click on the speculator layer to make it active and I'm going to switch from
00:59Normal to Linear Dodge in order to create this bright interaction.
01:04That's a little bit too much, you can see how we are clipping some of the
01:06highlights along the right half of his face.
01:08So I'm going to back off the effect by pressing Shift+5 in order to reduce
01:12the Fill value to 50%.
01:13Now let's turn the normal layer back on and now the task that confronts us, now
01:19he presents one of those classic problems inside Photoshop where one side of him
01:24is darker than his background, the other side is sometimes darker but often
01:29brighter than the background, and in many cases there is very little in the way
01:34of distinction between the foreground elements and those of the background.
01:38So there is a few different ways we could approach this.
01:40We did try out some calculations.
01:42It would actually take multiple calculations in order to select this guy.
01:46We could try multiple passes of the Color Range command.
01:50But I discovered that this is one of those lucky images that just happens to be
01:55perfectly suited to the Quick Selection Tool.
01:57So go ahead and grab the Quick Selection Tool there inside the Toolbox and make
02:02sure that the Auto- Enhance checkbox is turned on.
02:05I have my Brush cursor set to 30 pixels and I'm going to go ahead and paint in
02:10certain portions of the image like so.
02:12So I'm starting off with the head, I want to make sure to paint inside of the
02:15hair as well, so I can select as much of that as possible.
02:19The Quick Selection Tool is not going to do very good job of selecting into the
02:23tendrils of hair, however, we are going to follow this up with an application of Refine Edge.
02:27Now let's go down the dark side of his body over here on the left-hand side and
02:32that ends up miraculously selecting almost everything without jumping out of the
02:37image as the Quick Selection Tool is generally so fond of doing.
02:41All right, I'm going to paint up here into his shoulder as well.
02:45Your selection may end up varying, so we'll just see how things work out here.
02:49I'm painting inside of his knuckles, then into his thumb and that looks like
02:53I've pretty much got everything selected except for his collar.
02:56So I'll just click in there in order to select that.
02:59This is a fairly clumsy selection so far, but we have managed to create a
03:04selection outline around the figure of this man without selecting into the
03:08background, so that's a big bonus. All right!
03:11I'm going to switch back to the Rectangular Marquee Tool and then I'm going to
03:14go up to the Select menu and choose the Refine Edge command or you can press
03:18Ctrl+Alt+R or Command+Option+R on the Mac.
03:20Let's go ahead and zoom in to this guy so we can see what we are doing.
03:24I have my View options set to On White so I'm seeing the guy gets a white
03:27background which makes perfect sense because he is so dark in the first place.
03:31And then as opposed to applying a general amount of Edge Detection, I'm going to
03:36use my Refine Radius Tool to paint inside of the hair.
03:40So I'm just going to paint around the hair like so and he is got a lot of hair
03:44going into that background.
03:45It's very difficult to see where the hair begins and ends.
03:49That's actually kind of an advantage for us, because it gives us a little wiggle
03:53room during the compositing phase.
03:55Anyway, I'm going to paint up here over the top of his hair as well, maybe a
03:59little bit down on the left-hand side, and that looks like of course an absolute mess.
04:04But it's going to resolve better once we merge the layers together.
04:07Now I'm going to press the Alt key or the Option key on the Mac and drag along
04:11the top of the hair like so in order to bring back some of that opacity,
04:15apparently I lost the detail right there, so I'll click on it in order to add to
04:19Photoshop's recalculations.
04:21And then I'm going to paint ever so slightly down his face.
04:24Notice I'm just painting a little bit outside of the face line right there,
04:28because we had a harsh line in the first place.
04:30And I think that's going to do us pretty well.
04:32We have some other problems here and there but we can solve them manually.
04:35So I'll go ahead and click OK in order to accept the modification to
04:40the selection outline.
04:41Now we need to convert the selection into a layer mask and I'll do that by
04:45dropping down to the Add Layer Mask icon at the bottom of the Layers Panel and
04:49clicking on it, which is not bad.
04:51Now I wouldn't go so far as to say it's altogether acceptable, which is why we
04:55need to spend a few minutes manually refining the mask as well as applying some
04:59blending modifications as we will do in the next exercise.

Refine, filter, and blend
00:00In this exercise, we're going to finish off our composition by manually
00:04enhancing the mask and then applying some blending modifications.
00:08Let's start things off by Alt+ Clicking or Option+Clicking on the Layer Mask
00:12Thumbnail there in the Layers Panel and I'm going to zoom in on this guy's head
00:16and you can see that we have some problems around his face.
00:19So I'll grab the Brush Tool which I can get by pressing the B key of course.
00:24Right-click inside the Image window, let's take that Hardness value down to 0%
00:28and then I'm going to increase the size of my cursor by pressing the Right
00:31Bracket key a few times.
00:33Press the X key to make sure my foreground color is Black and then I'll
00:37paint along the edges.
00:39Made a big huge mistake, I forgot to change the Blend Mode.
00:42So I'll press Ctrl+Z or Command+Z on the Mac.
00:44Press Shift+Alt+O or Shift+Option+O in order to switch the Mode to Overlay
00:49and then try painting again, and that provides us with much better results of course.
00:54Press the X key to switch the foreground color to White and then I'm going to
00:58paint along the eyebrow and down here along the jaw as well.
01:01You could expand the hair a little bit if you want in places but I wouldn't go
01:05too far with that, and that's about all we're going to do with Overlay painting.
01:09We do have some problems with the shoulder details however, so I'm going to
01:13Alt+Click or Option+Click to once again switch to the composite image and then
01:17I'm going to Shift+Click on the thumbnail to turn the Layer Mask off.
01:21Right-click inside the Image window, let's take the Hardness value up to 70%.
01:24I want a smaller cursor too, I'm going to take that down to 20 pixels let's say.
01:29Press the Enter key a couple of times in order to accept that modification.
01:33You may recall from the Fundamentals course that you can paint inside of a layer
01:37mask even when it's not visible.
01:39So I'm painting with white, I'm just going to paint down this shoulder as I see
01:43it to about there, should do the trick and then I'll Shift+Click in the Layer
01:48Mask Thumbnail once again to turn it back on.
01:50It looks like it didn't quite get this detail as well as I like.
01:53So I'm going to click inside of it again in order to expand the mask and the
01:57problem this time is I'm painting with the Overlay Blend Mode.
02:00I don't want that, so I'll press Shift+ Alt+N or Shift+Option+N on the Mac in
02:04order to turn the Blend Mode off, so I can paint normally.
02:07I'm going to Shift+Click on that Layer Mask thumbnail again so I can see the
02:10original unmasked image.
02:12Paint down the shoulder to about there.
02:14Shift+Click in the Layer Mask thumbnail to see what I've done and it
02:17actually looks pretty good. All right!
02:18I'm going to zoom out by pressing Ctrl+0, Command+0 on the Mac.
02:22Press the M key to switch back to the Rectangular Marquee Tool.
02:26This image provides us with a few challenges, even though, I think it's a great photograph.
02:32It's a little bit brittle.
02:33There is a lot of noise and weird details in the shadows, and currently the
02:37shadows are overly dark, and I'd like to bring some life into them.
02:40And I'm going to do that by applying the Shadow Highlight command as a Smart
02:44Filter, which means I want to convert this layer to a Smart Object but I don't
02:48want the Layer mask to be part of that Smart Object.
02:50So I'm going to do that thing where I move the layer mask to a different layer,
02:54then with normal selected I'll go up to the Layers Panel fly-out menu, choose
02:58Convert to Smart Object and then move the layer mask back on to that layer.
03:04Now I'll click on the Layer Thumbnail itself, the Smart Object Thumbnail and
03:08I'll go up to Image menu choose Adjustments and choose Shadows/Highlights, and
03:13you can see that the default value is bringing out all kinds of noise inside the
03:17Shadow details of this image.
03:19So with my Show More Options checkbox on, I'm going to take that Shadow Amount
03:24value down to 10%, the Tonal Width value of 50% is fine, and I'm going to
03:28increase the Radius like crazy to 200 pixels.
03:30I'm going to leave the Highlight Amount set to 0%, which means we don't have to
03:34worry about any of the other values and now I'll click OK.
03:38Now we need to make sure that this Smart Filter affects the
03:40luminance information only.
03:42So double-click on the Slider icon to bring up the Blending Options dialog box
03:46and switch the Mode from Normal to Luminosity, that way the color goes
03:51unmodified, then click OK in order to accept that change.
03:55We don't need the Filter Mask so I'm going to right-click on it and choose
03:58Delete Filter Mask, and I'm going to do that using a layer effect.
04:02So I'll drop down to the fx icon, click on it, choose Color Overlay.
04:06By default that's going to turn him entirely red.
04:09I want a sepia color, so I'm going to click on that color swatch and I'm going
04:12to change the H, S and B values to 25 apiece like so, that gives us a kind of
04:19dull brown, click OK.
04:21Change the Blend Mode to the opposite of Luminosity which is Color, so that we
04:25are keeping his luminance information and just modifying the hue and saturation,
04:30and then I'm going to take the Opacity value down to 50%.
04:32All right, he is looking pretty good but because he is noisy and what I mean is
04:39if you go ahead and zoom in here you can see a lot of posteration going on
04:43inside this color detail, and I want to sort of hide that a little bit.
04:48Now I could have found a better image to work with in the first-place, but
04:51oftentimes you're going to find yourself confronted by that perfectly
04:54acceptable photograph.
04:55In other words, compositionally it's great and so forth, but it's a low fragile
05:00in places, and so here's one way to sort of cover that up.
05:03I'm going to press Ctrl+0 or Command+ 0 on the Mac to zoom out and the first
05:07thing I'm going to do is reduce the Opacity value by pressing 77 in a row so
05:12that takes the Opacity value down to 77%.
05:15We can see through his shoulders a little bit.
05:17I don't want to see through his wristwatch and his elbow to the sides of these
05:22bars, so I'm going to create a kind of backing layer, by first Ctrl+Clicking
05:28or Command+Clicking on the Layer Mask thumbnail in order to load his outline as a selection.
05:33Then I'll click of a speculator layer to make it active and I'll create a new
05:37layer by pressing Ctrl+Shift+N or Command+Shift+N on the Mac.
05:40I'll call it back and click OK.
05:43Now I'm going to grab my Gradient Tool, which I can get by pressing the G key
05:48and notice my options up here, these are all the default settings.
05:51I'm creating a Linear Gradient, the Mode is Normal, Opacity 100% and so forth.
05:56I have switched the gradient style however to the second one in, which is
06:00Foreground to Transparent, and also very important, my Foreground Color is set to Black.
06:05And I'm going to drag from about the top of his arm right here, and while
06:10pressing the Shift key I'll end my drag at the bottom of his chin in order to
06:14create this backing layer that hides the sides of those blocks.
06:18Now I'll press Ctrl+D or Command+D on the Mac in order to accept that modification.
06:23Press the F key a couple of times in order to switch to the Full Screen mode and
06:27this is the final version of my masked composition.
06:31Thanks to our ability to mix layer masking along with a member of the Lighten
06:35Blend Mode family here inside Photoshop.

6. The Contrast Modes
Overlay, Soft Light, and Hard Light
00:00Over the course of this and in the next exercise I am going to introduce you to
00:04all seven of the contrast modes.
00:06In this exercise, I'll start off with the primary three modes which happen to
00:11appear first in the list.
00:12Those are Overlay, Soft Light and Hard Light, all of which are designed to mimic
00:17a combination of Multiply and Screen, working together.
00:21If you get a font warning when you open this image, don't worry about it,
00:24Photoshop will still allow you to see the text as it was originally rendered.
00:28Notice in the background here I have this photograph of this pile of leaves.
00:32So that will serve as the backdrop for each one of our effects.
00:37Now if I switch over to my next layer comp, you can see for the sake of
00:40demonstrating the Darken and Lighten modes, I have set up two side-by-side
00:44gradients both of which appear on different layers you can see here, one is
00:47called left, one is called right.
00:49We've got a black to white gradient over here on the left-hand side and a black
00:53to white gradient over here in right hand side.
00:55I'll be applying the Darken mode to the left hand gradient and the Lighten mode
00:59to the right-hand gradient.
01:01Because white is always the neutral color for any of the darken modes, that
01:05white right in the center will drop away and because black is always a neutral
01:09color for any of the Lighten modes, this black edge in the center will drop away
01:14and as a result the two layers will appear to seamlessly merge together.
01:19Meanwhile, where the contrast modes are concerned, I'll be applying them to this
01:23large gradient that stretches across the entire width of the image from black
01:27over here on the left-hand side to white over here on the right-hand side and
01:31where all the contrast modes are concerned, except for Hard Mix, it's the only
01:35exception, 50% gray is a neutral color right there dead center.
01:42So let's see what this looks like.
01:44In this slide, I have gone ahead and applied the Multiply mode to the
01:47left-hand gradient, so this left gradient, here in the Layers panel, you can
01:50see multiplies aside.
01:52And then I've applied the Screen mode to the right layer which is the right-hand
01:56gradient and you can see the Screen mode applied as well.
01:59So as a result, we get a darkening effect over here on the left and we get a
02:02lightning effect over here on the right and the point at which the two layers
02:06meet up with each other, right there in the center, that's where the luminance
02:09levels entirely drop away.
02:12Compare that to the Overlay mode, what you'll hear people say about the Overlay
02:16mode is that it's that classic combination of Multiply and Screen.
02:21However, if you look at Multiply and Screen by comparison and then you look at
02:26the Overlay mode, they don't look very similar at all.
02:28We do have a bit of darkening happening over here on the left-hand side and we
02:33have some lightning appearing over here on the right-hand side, but it's by no
02:37means as much as we were seeing with Multiply and Screen. Here is the thing.
02:40The basic blending formula associated with Overlay is absolutely equivalent in
02:46terms of the way it works to Multiply and Screen and yet the reason it looks so
02:50different is because Overlay favors the composite background, in our case, the
02:55leaves, over the active layer in our case the gradient and so as a result, it
03:00produces a muted effect by comparison to Multiply and Screen working together.
03:05And yet, it is the foremost of the contrast modes, its super useful as you'll
03:10see in future exercises.
03:12Now if Overlay ends up being too much and you want something that's more
03:16subtle, then, you'll want to switch to the next mode which is Soft Light and
03:20notice that we have some darkening over here on the left-hand side and some
03:24brightening over here on the right-hand side, but not nearly as much as we saw
03:28a moment ago with Overlay.
03:29You can compare that to the original image.
03:32This is the base leaves image by itself.
03:35Notice that things brighten up over here on the left side;
03:37they darken up over here on the right-hand side because this full grad layer is now turned off.
03:42Alright! Now by contrast, here is the Hard Light mode.
03:47So we are seeing an awful lot of darkness over here on the left side and an
03:50awful lot of the lightness over here on right-hand side.
03:54Now it uses exactly the same formula as Overlay.
03:58So it's really the exact same blending computation and yet, we end up getting a
04:02very different result and that's because Hard Light favors the active layer
04:07that is the gradient instead of the background leaves and as a result Overlay
04:13and Hard Light are said to be commuted versions of each other, just in case you
04:17ever hear that term.
04:18Now just for comparison, here are the Multiply and Screen modes.
04:22So a lot of darkening happening over here on the left side, a lot of brightening
04:26happening over here on the right-hand side.
04:28Notice that the gradients drop away uniformly so very smooth effects, which is
04:33also true of the Hard Light mode which you can see now.
04:36So Hard Light if you were think of anything as being the equivalent of Multiply
04:40and Screen working together that would be Hard Light.
04:43If you prefer to turn the effect on his head and favor the background image,
04:47instead of the active layer then you would apply Overlay and if you're looking
04:51for something more subtle then go with Soft Light and that in a nutshell, we'll
04:55be seeing more of them.
04:56But that's how the Overlay, Soft Light and Hard Light modes work here in Photoshop.

Vivid, Linear, and Pin Light
00:00In this exercise I'll introduce you to the next three contrast modes which are
00:04Vivid Light, Linear Light and Pin Light.
00:07We're looking at that combination of Multiply and Screen that is the Hard Light
00:11mode, as you might imagine the other contrast modes are combinations of other
00:16Darken and Lighten pairings.
00:18For example, let's start with Color Burn and Color Dodge, I've gone ahead and
00:23assigned Color Burn to the left hand gradient and Color Dodge to the
00:27right-hand gradient.
00:28We end up with these vibrant colors.
00:30We have this smooth transition in the middle because white drops out in the case
00:34of Color Burn and black drops out in the case of Color Dodge, right here in the
00:38middle of the image.
00:39However, we end up with a lot of clipping as well.
00:42Specifically, we're clipping the shadows to black over here on the left and
00:45we're clipping the highlights to white on the right.
00:48So Photoshop is seen fit to allow us to mitigate that clipping by reducing the
00:53Fill value as opposed to the Opacity value which is why both of these modes are
00:58members of the Fill Opacity Eight.
00:59The same goes for the mode that's based upon them which is Vivid Light.
01:05Vivid Light is a combination of Color Burn and Color Dodge working together.
01:09It results in clipping as well.
01:10We're clipping the shadows to black clipping the highlights to white.
01:14We can mitigate that clipping using the Fill value and it looks like this by the way.
01:19If I were to take that Vivid Light and reduce the standard Opacity value to 50%,
01:23what we are doing is we're taking the composite effect and mixing it 50-50 with
01:29the underlying leaves layer.
01:31And we end up getting this fairly drab effect here.
01:34You may still encounter some clipping, whereas if you reduce that Fill value to
01:3950%, you're left with a vibrant image like this one here, which is exactly what
01:45you want, out of a contrast effect inside Photoshop.
01:49So remember these over-the-top effects specifically in the case of this
01:52exercise, Vivid Light and Linear Light can be mitigated using the Fill value. Alright!
01:58Let's take a look at Linear by way.
02:00First I'll show you the Linear Burn and Linear Dodge modes as applied to
02:04those two independent gradients, the left and right layers here inside the Layers panel.
02:09A lot of shadows clipping the black, a lot of highlights clipping the white,
02:13which is why both of these modes are members of the Fill Opacity Eight, as is
02:17the mode that's based on them which is Linear Light.
02:19So Linear Light is a combination of Linear Burn and Linear Dodge.
02:23Its effects can also be mitigated by the Fill value.
02:26So here is a comparison.
02:28Linear Light set to a standard Opacity of 50% ends up giving us this kind of
02:33filmy effect as if we are looking through a dingy window.
02:37Whereas, Linear Light, set to a Fill value of 50%, gives us this lustrous and
02:43comparatively rich effect right here.
02:46Now the final mode that I am going to show you is actually the least of the bunch.
02:50So imagine if you will, a combination of the Darken modes and the Lighten
02:54modes working together.
02:55So in this case, I've assigned a Darken mode that is the mode that's called
02:59Darken to the left layer here and I have assigned the Lighten mode as you can
03:04see to the right layer.
03:06What we end up getting is this sudden drop-off.
03:09Notice that we have a bunch of blackened darkness over here on the far left hand
03:13side then we sort of revealed the leaves at about this location and then the
03:18effect entirely goes away and stays away till about here where we get this kind
03:22of filmy overlay and then everything goes white.
03:26The same happens, I'm afraid, with Pin Light which is based on Darken
03:31and Lighten together.
03:32So I'll tell you this is not a mode that I use very often, it doesn't frequently
03:37give you desirable effects.
03:39So if you find yourself not turning to it 99% of the time, don't be surprised.
03:44I will tell you one last thing about Pin Light;
03:45it is not a member of the Fill Opacity Eight.
03:49So there is nothing you can do to mitigate its ugliness.
03:52In the nice exercise, I will demonstrate that mode that may seem at first,
03:56like the worst of the contrast modes, but it's actually quite powerful indeed, Hard Mix.
Collapse this transcript
The amazing Hard Mix mode
00:00In this exercise, we'll demonstrate the final contrast mode, Hard Mix.
00:05So here we are looking at the Pin Light effect.
00:07If I move to the next layer comp, you can see the effects of Hard Mix which at
00:12first are truly appalling.
00:14Now what's happening is that Photoshop is applying the Vivid Light mode.
00:18So Hard Mix uses exactly the same formula as Vivid Light and then it goes ahead
00:24and reduces the luminance levels to just black and white on a channel by channel
00:29basis which is why you end up getting this highly posterized effect, where all
00:33the pixels either turn black or they turn white or the they turn one of the
00:37primary colors, meaning red, yellow, green, cyan, blue or magenta.
00:42In our case, because we have a very warm image, we're just left with the
00:45yellows and the reds.
00:48The great news is that this is the classic Fill Opacity Eight mode, the one
00:53that responds altogether differently to the Fill value than it does to the Opacity value.
00:58So first just so that you can see how this mode compares to Vivid Light, I'll go
01:03ahead and switch to the next slide.
01:04This is actually the Vivid Light effect.
01:07If I click on the full grad layer here inside the Layers panel, you can see that
01:10I've assigned the Vivid Light mode.
01:12The difference between your standard Vivid Light which looks like this and Hard
01:17Mix is the fact that we're thresholding the channels.
01:21In this case, I'm using a levels adjustment layer to reduce the colors to black
01:25and white on a channel by channel basis, Hard Mix does it automatically.
01:29Anyway, I just wanted you to see that that's how it works.
01:32Now let's get a sense of what happens when you reduce the opacity of the effect.
01:36In this case we're back to using the Hard Mix mode and I've taken the standard
01:40Opacity value down to 50%.
01:42So what's happening is Photoshop is taking that composite version of the image
01:47and mixing it 50-50 with the underlying leaves.
01:51So this area, for example that was formerly black at 100% opacity, is
01:56now turning to darkness, so that we can see some standard leave
02:00transitions happening.
02:02But at any point where we are transitioning to a different color, you're going
02:05to see posterization throughout the composite image which is, I would think,
02:11rarely desirable whereas if you reduce that Fill value down to 50% instead, you
02:16can see that we get a remarkably different effect that's rich and vivid
02:21throughout the composition which well, the color saturation maybe a little bit
02:25too much, is not a half bad effect.
02:28Compare that to Vivid Light, set to a Fill Opacity value of 50%, the big
02:34difference here is that the grays drop away and become transparent where Vivid
02:39Light is concerned and for the matter where any of the other contrast modes are
02:43concerned as well, whereas if I switch back to Hard Mix here, you can see that
02:48even those leaves in the center of the image are being affected by the mode,
02:52which means that you can take the Opacity value very low indeed where this
02:56effect is concerned.
02:58Here is Hard Mix, set to a standard Opacity value of 25%, we still end up with a
03:04drab and posterized composition, whereas if I take Hard Mix down to a Fill value
03:09of 25% instead, I have vibrant colors across the entire image.
03:14But even at a very low Fill value of 25 %, Hard Mix typically produces a more
03:20pronounced effect than something like Soft Light.
03:23Notice here that we do have some darkening on the left hand side, some
03:26brightening on the right-hand side, the effect drops off in the center, but we
03:30don't have nearly that degree of color saturation.
03:34So really, the moral of the story is if you want the most subtle contrast effect
03:39possible, then you go with Soft Light, if you want the highest impact effect of
03:43them all, plus some intensely saturated colors, then you'll want to go with Hard
03:47Mix subject to a reduced Fill value.

Two variations on a single mode
00:00In this exercise we'll see how Overlay and Hard Light are actually variations on
00:05the very same blend mode, it's just a matter of which layer is in front, and
00:09I'll show you something you can do with that information as well.
00:12We've got this portrait shot on top, and then below that this sort of cave
00:16wall in the background.
00:18All right, I'm going to go ahead and turn the portrait back on, I should know
00:21that both of these images come from a Fotolia Image Library, about what you can

00:26Now I'm going to go ahead and change the blend mode associated with that
00:31portrait layer to Overlay, and that'll create an effect much as if we had
00:36somehow projected the image of this woman onto this surface.
00:41So the shadow details on her face are burning into the background, the
00:45highlights are brightening the background, and so forth.
00:48So it's almost a matter of wrapping one texture around another, as we'll see in
00:52subsequent exercises.
00:54All right, now I'm going to click on the Wall layer and I'm going to change its
00:56blend mode Hard Light.
00:58Now that's not going to make any difference as you can see here and the reason
01:03is that blend modes only work down the stack.
01:06If there's nothing below a layer, you can change its blend mode to anything you like.
01:11However, the blend mode is not going to work, because there's nothing to blend
01:15with, in the background.
01:17But notice now, if I change the order of these two layers, so wall is on top and
01:22portrait is underneath, the effect again does not change, and that's because
01:27Hard Light and Overlay are commuted versions of each other, that is to say, when
01:32Hard Light is on top, you get the same effect as when Overlay is on top.
01:38When an Overlay layer is on top, then you're emphasizing the layer below,
01:42as we're in this case.
01:44If I was to ask you which layer is the most prominent, I would gather that you
01:48would say the cave wall, because it looks as if the cave wall is actually what
01:51we're seeing with her projected onto it.
01:54Meanwhile, when you set a layer to Hard Light, then it takes precedent over the layer below.
02:00So to just give you a sense of what it look like if we went the other way
02:02around, if we gave the portrait layer precedent instead, I'll press Shift+Alt+O
02:08or Shift+Option+O on the Mac, to change that wall layer to the Overlay mode, you
02:12can see that that shifted its appearance onscreen.
02:15I'm now going to select the portrait layer, and I'm going to press Shift+Alt+H
02:19or Shift+Option+H on the Mac to change its blend mode to Hard Light, that's not
02:23going to change anything, because as before, there's nothing underneath a
02:27portrait layer to blend with.
02:29However, notice now, if I change the order of these two layers, so she's on top
02:34and the wall is on the bottom, we're getting the exact same effect.
02:37Once again, because Overlay and Hard Light are commuted versions of each other.
02:42When a layer is set to Hard Light it takes precedent just as this portrait shot
02:46is now taking precedent inside of the composition.
02:50When the wall is on top and set to the Overlay mode, it gives precedent to
02:54the layer below it, which is still portrait, so we end up with the exact same effect.
02:59Now one of the reasons I mention this is not just because it's interesting, but
03:03also because I think it will help you navigate through these modes and make
03:07sense of them when you're applying them on your own.
03:09For example, I'm going to grab that portrait layer, move it on top and I'm
03:12going to press Shift+Alt+N or Shift+ Option+N on the Mac, in order to restore it
03:17to the Normal mode.
03:18Now let's say I want to enhance the contrast of this image while enhancing its
03:23color as well, you can do that using an empty adjustment layer set to one of
03:28the contrast modes.
03:29So for example, if I press the Alt key or the Option key on the Mac and click
03:33that black white icon and choose for example Brightness/Contrast and then I'll
03:38just call it dummy, because I'm not going do anything with it, click OK.
03:42In other words I'm not going to change either the values, I'll go ahead and
03:45collapse the Adjustments panel and then I'll change the blend mode from Normal
03:50to Overlay and we end up getting this enhanced contrast effect that ends up
03:55benefiting this image quite nicely, because after all it was a pretty low
03:59contrast image in the first place.
04:01Now if you feel like there is too much contrast, you can to switch from Overlay
04:04to Soft Light and you'll end up achieving a different effects, so here's the
04:08original version of the portrait shot and here's a versions subject to
04:13essentially setting itself to the Soft Light mode.
04:16Now what you'll typically hear from folks is if Overlay isn't enough, then you
04:21can bump things up by switching the Hard Light.
04:24However, that's not going to make any difference in this case, because it's the
04:28same darn blend mode, it just matters which layer is on top.
04:31Well, this dummy layer is essentially a copy of the portrait layer, so they're
04:35both the exact same layer, so we're going to get exactly the same effect and
04:40that's something to bear in mind when you're working with your own images.
04:43So where this sort of approach is concerned, if Overlay isn't quite doing it for
04:48you then you want to bump it up all the way to Linear Light, that's going to be
04:53your high contrast mode when you're working with an adjustment layer for
04:56example, that of course is going to be too much, you're going to see all sorts
05:00of clip shadows and blown highlights, so then at this point you would reduce the
05:05Fill value, I'm going to press Shift+5 to take that Fill opacity down to 50%,
05:10which isn't quite enough, so I'll go ahead and try Shift+2 instead, to take it
05:14down quite a bit further.
05:15So we now have Linear Light combined with a Fill value of 20%.
05:19If I turn off that dummy layer, you can see that's making a big difference.
05:22So this is the original fairly low contrast version of the image, and this is
05:27the newly enhanced version.
05:29Thanks to the application to an Empty Adjustment Layer of Linear Light and a
05:33Fill Opacity of just 20%.

Adding clarity with a contrast mode
00:00In this exercise I'll show you a couple of really great filtering effects that
00:04you can pull off using Overlay and a couple of the other contrast modes.
00:09Now the first thing I'm going to do is duplicate this layer.
00:11Press Ctrl+Alt+J or Command+Option+J on the Mac, and I'll call this layer
00:16portrait and then click OK.
00:19And now, just so that we have as much flexibility where the filtering process is
00:22concerned as possible, let's convert this layer to smart object by going up to
00:26the Layers panel fly-out menu and choosing the Convert to Smart Object command,
00:31and now let's say we want to apply a kind of sharpening effect.
00:35I'll go up to the Filter menu and then I'll choose the High Pass command, and
00:39because of the way it's build High Pass does a better job of eliminating
00:44clipped highlights and shadows in this Smart Sharpen command does, which often
00:49makes it a better tool for sharpening portraits, so I'll go ahead and choose that Command.
00:53Now initially if I were to set the Radius to something like 3 pixels let's say,
00:58the effect is not going to look too good.
01:00We're sending most of the image to gray, and we're just keeping a little bit of
01:04shadow and highlight detail around the edges, but that's the whole point.
01:08The beauty of this is gray is neutral when you apply Contrast modes, so you can
01:13make all that grayness go away.
01:15So I'll click OK in order to accept that affect.
01:18I'm going to right-click inside of that Filter mask and choose Delete Filter
01:21Mask to get rid of it, and then I'll double click on a little slider icon to
01:26bring up the Blending Options dialog box, and I'm going to switch the mode to Overlay.
01:31and we end up with this sharpening effect right here.
01:35Now I'll go ahead and click OK in order to accept the change.
01:38I'll zoom in a little bit as well, so that we can see her eye a little more
01:41closely, and I'll turn off the effect for a moment.
01:44This is the before version of the image, and this is the after version.
01:48So it's pretty subtle right now, and it might be a little too subtle for your taste.
01:53In which, case double-click on the slider icon again, and now let's go ahead and
01:57switch the mode not to Soft Light, because we don't want to reduce the effect,
02:01although if we did, that would be a great mode.
02:03Not to Hard Light, because we're not going to get a different affect, because it
02:07is the same darned images.
02:08Vivid Light isn't really what we're looking for this effect.
02:11If you wanted to bump it up, then you'd go for Linear Light and that's going to
02:15give you the most heightened effect possible.
02:17There's something to note about this Opacity value, you can go ahead and reduce
02:22it, but it's not Opacity, it's Fill Opacity.
02:26Let me show you that that's the way it works.
02:28I'm going to switch to Hard Mix for a moment here, so you can see just how
02:32ridiculously over-the-top the effect is.
02:35If I reduce it to 50%, notice how well it merges, that's not a standard 50%
02:40Opacity, that's the 50% Fill Opacity and so not only does this opacity value
02:46behave as Fill Opacity here inside the Blending Options dialog box, but it
02:50behaves that way when you apply layer effects as well.
02:54So bear that in mind, and by the way, it's not something to watch out for, it's
02:58strictly great news.
03:00Anyway, I'm going to switch this back to Linear Light, and I'm going to crank
03:04the Opacity value back up to 100% for now, so I can show you, if I zoom out
03:09here, you can pretty clearly now see the effects of the sharpening, this is
03:13the original version of the image, if I turn the effect off, and this is what
03:17it's look like now.
03:18Let's say though you're not really looking for sharpening, you're looking for
03:21clarity, which is to say a little bit of edge contrast, but something with a
03:26wider diameter, then double-click on where it's High Pass to bring back up the
03:30High Pass filter dialog box, and let's crank the Radius value up to a 100
03:35pixels now, and click OK.
03:37Obviously, that's too big of an effect, so then you double-click on the slider
03:42icon and take that opacity value down to say 20% or so and click OK, and because
03:49it's Fill Opacity, we end up getting this pretty darn subtle effect, this is
03:53what the image looked like before, and this is what it looks like now.
03:57So the result is a subtle application of clarity.
04:01Thanks to this very flexible application of the High Pass filter subject to
04:06Overlay and Linear Light.

Creating a glowing, soft-focus effect
00:00In this exercise I'm going to show you another really great contrast
00:04modes filtering effect.
00:06That's pretty much the opposite of what we saw in the previous movie.
00:09Rather than adding clarity or contrast, we're going to add a kind of glow to
00:14the image using Gaussian Blur, and even if you've seen this effect demonstrated
00:18before, I have come up with a variation on it, that I think makes it a lot more successful.
00:23And with this portrait smart object layer selected, I'm going to turn off High
00:28Pass, because we don't want it on for this effect.
00:31Then go up to the Filter menu choose Blur and choose Gaussian Blur, and I'm
00:36going to apply a big Radius value of 20 pixels, and then click OK.
00:42The next step is to double-click on the slider icon and change the mode from
00:46Normal to Overlay, and you can experiment with the other contrast modes if you
00:51want to, but I'm going to stick with Overlay, and I'll click OK.
00:55Now you can see how that does give the image a kind of balance.
00:58If I turn Gaussian Blur off, this is the original version of the photograph, and
01:03then this is the modified version, so it servers a couple of different purposes.
01:07It's great if you just want to add a kind of bouncing glow effect, but it can
01:11also be useful for covering that pores and other skin details and blemishes.
01:16However, here is the problem.
01:17Notice the saturation levels when I turn Gaussian Blur off, and then when I turn it back on.
01:23Basically we're getting a heck of a lot more saturation, and it may work to the
01:28images advantage, but then again, it may not.
01:31The problem is and the reason we didn't see that where High Pass was concerned,
01:36is because High Pass was generating grayish results, where Gaussian Blur is
01:41generating very colorful results.
01:43So the colors are building on each other, thanks to the Overlay mode, and we end
01:48up punching out those saturation values.
01:50What if that's not what you want, but if you want to leave that saturation alone?
01:54Well, you do a couple of things.
01:56First of all you double-click on that slider iconic again, and you reset the
02:00mode from Overlay back to Normal, and then you click OK.
02:04Now for this to work, you need two separate versions of the image, one of which
02:07has to be a smart object as ours is, and then another version, which is the
02:12original smart object or not.
02:15Now you go up to the blend mode pop-up menu here in the Layers panel and you
02:19change it to Overlay.
02:21We get the exact same effect by the way, but now we have a little more control
02:25over what's going on.
02:26Now I want you to press the Alt key or the Option key on the Mac, click the
02:30black white icon at the bottom of the Layers panel, and choose the Vibrance
02:34command this is the best adjustment for this purpose and let's go ahead and
02:37call this new layer desat and turn on the checkbox that says Use Previous Layer
02:42to Create Clipping Mask, click OK, because we're clipping this adjustment layer
02:47or reducing the contrast of the smart object layer, but not the composition overall.
02:52Now notice we take the saturation value all the way down to that should be
02:57-100, then we're actually depleting the saturation of the overall image, that's not what we want.
03:04Instead if you want to maintain the original image saturation, you take that
03:08saturation value down to -50, and that's it, don't touch the vibrance.
03:13I'll just go ahead and close the Adjustment panel and you can see that if I turn
03:17off this smart object layer now, that's the original version of the image,
03:21that's the original level of color saturation as well.
03:24If I turn the portrait layer back on, you can see that we have the same level of
03:29color saturation, while still maintaining that nice bounce of glow, from the
03:34Gaussian Blur filter, combined with Overlay.

Blending an image with a paper texture
00:00In this exercise I'm going to show you how to map our artistic surface
00:04texture onto an image.
00:06And let's go down here to the Black & White icon once again, press and hold
00:09the Alt key or the Option key on the Mac and go ahead and choose the Pattern command.
00:13In order to create a New Pattern Fill layer and we'll call this layer
00:16texture and then click OK.
00:19Now inside the Pattern Fill dialog box, you'll be able to select from just two
00:23patterns by default.
00:24Neither of which are all that useful, but there is a bunch of other patterns to choose from.
00:29To get to them click this right pointing arrow-head and then choose one of these
00:32libraries down here at the bottom of the fly-out menu.
00:35I'm going to go with Artistic Surfaces, and then click on the Append button in
00:40order to load those up and keep the original two patterns.
00:43And I'm going to start with this pattern here, it's called Hard Charcoal light,
00:48and I'll click on it and then I'm going to change the Scale to 200% like so.
00:53Now all of these surface textures have a lot of gray in them and that gray is
00:57going to drop out if we change the blend mode assigned to this layer to one of
01:01the contrast modes such as Overly let's say.
01:04That's not really the effect I'm looking for, I wanted to look as if for face is
01:09actually sort of mapped into the texture, and so I'm going to press the Escape
01:15key in order to deactivate that blend mode and then just press Shift+Alt+N or
01:19Shift+Option+N on the Mac in order to restore the normal mode.
01:22And now let's go ahead and convert this texture to a smart object, so we can
01:26keep it around and modify it later if we want to.
01:29Click on the Layers panel fly-out menu and choose Convert to Smart
01:33Object command like so.
01:34Then let's turn this into a real texture by going up to the Filter menu,
01:39choosing Stylize and then choosing the Emboss command.
01:43For this sort of effect you can change the angle to anything you please, but I
01:48recommend you set the Height value to just 1 pixel and Amount of 100% is just
01:53fine, and then click OK.
01:56And now we have something closely resembling a texture and it's got a lot of
02:00gray in it, which means we can dropout the gray and just keep the highlights and
02:04shadows by switching to one of the blend modes.
02:08Now I always recommend you start off with the Overlay mode, see what you think.
02:12If that's not quite enough, now you can switch to Hard Light, because you're
02:16working with two totally different images this time around, and you will create
02:20an enhanced effect, if that's still not enough, well then just go ahead and bump
02:24it up to Linear Light and see what happens.
02:27Now of course this is too much of an effect, so I'm going to back it off by
02:31pressing Shift+5 to reduce the Fill opacity to 50%.
02:36Now at this point let's say, you're thinking, well, it's a pretty cool paper
02:39texture, makes the image look a little painterly or as if you've printed it on
02:43nice stock, what have you.
02:45However, this isn't quite the texture you're looking for.
02:48Well then, all you need to do to switch out to texture is double-click on the
02:51Smart Object thumbnail here inside the Layers panel.
02:53If you get the alert message, just click OK, that'll open the image and an
02:57independent window like so.
02:59You'll end up with the Texture layer and then this empty Layer 1 below it, just
03:04go ahead and get rid of Layer 1 by clicking on it and pressing the Backspace or
03:07Delete key, and then double-click on that thumbnail to bring up the Pattern Fill dialog box.
03:13Let's go ahead and switch to a different pattern.
03:15The one I think works really well with this images is Coarse Weave, so I'll go
03:19ahead and click on it to select it, then you could if you wanted to, you could
03:22modify the scale value to make it bigger or smaller or what have you.
03:26However, this is going to work out fine, so I'll click OK and then just go ahead
03:30and close the image, and click Yes to save the image here on the PC.
03:34You'd click the Save button on the Mac, and you change out that texture.
03:38So if I press Ctrl+Z or the Command+Z on the Mac, this is that original texture
03:42and then this is the new one.
03:44The new texture is over the top, it's just too big, so I'm going to press
03:48Shift+2 to reduce that Fill Opacity value to 20% and we end up with this nicely
03:54textured effect right here.
03:56And you know what, I think we're going to be able to see it better if I press
03:59the F key a couple of times to switch to the Full Screen mode, and that's how
04:03you map a surface texture onto an image, using a combination of the Emboss
04:08filter along with a Contrast mode.

Turning flesh into stone
00:00In this exercise I'm going to show you how to use the Overlay mode in order to
00:04wrap a texture around the surface of a person's face.
00:08And it turns out to be something of morale of the story here.
00:11This dude is making this kind of I'm just crazy enough to do it face.
00:16And just as your mother probably told you, if you make a face like that long
00:20enough, it's going to turn to stone, and that's what we're going to do.
00:24We're going to go ahead and wrap this stone texture around his face, so it looks
00:29like he's been turned into a kind of statue.
00:32And here is how we're going to make it happen.
00:34If you go to the Channels panel you'll notice that I've set up some alpha
00:37channels for you in advance.
00:39There is this face channel right there, which represents of course most of the guy's face.
00:43We're missing some details on his chin and so forth, but that's okay.
00:48I didn't get his neck however;
00:49I wasn't able to select the neck at the same time, so I've selected the neck
00:53which is very dark region inside of this image in a separate paths.
00:57So we're going to go ahead and add these two mask together.
01:00And one way to do that is to go up to the Image menu and choose the Calculations
01:04command, and then we get select the two masks one of which is called face the
01:09other one's called neck, and because we want to add them together, we want to
01:12magnify their bright parts, then we would change the blend mode to Screen, and
01:18that's how you add two mask together inside of Photoshop, And then click OK and
01:23you'll end up with yet another Alpha channel, and we can call this one mask.
01:28Now I Ctrl+click on it or Command+Click on the Mac and then switch back to the
01:32RGB image, and I'm going to turn on that stone layer, click on it to make it
01:37active, and then drop-down to the Add layer mask icon and click on it in order
01:41to mask that texture into the guy's face.
01:44All right, now just the matter of changing the Blend Mode to Overlay, so that
01:49we can get a sense of how the texture and the face are going to interact with each other.
01:53Now there are a couple of issues I have here, one is, I don't really want the
01:57texture mapping into his eyes, because I think it will look better if his eyes
02:01are all naturally flashy.
02:03I created some Paths in advance, I'm going to switch over here to the Paths
02:06panel, and you can see that I've got these paths, we'll go ahead and zoom in on
02:11him and I'll select him too with a Black Arrow tool.
02:14I'll click on one and Shift+Click on the other so that you can see these path
02:18outlines that I drew with the Pen Tool;
02:20you can see they have a certain clockwork Orange quality to them.
02:24What I really want to do is convert them to a selection, so I'll Ctrl+Click or
02:28Command+Click on the eyes path in order to select the eyes, then I'll switch
02:33back to the Layers panel, make sure that Layer mask is selected there inside the Layers panel.
02:38Press the D key in order to establish the default foreground and background
02:41color and then press Ctrl+Backspace or Command+Delete on the Mac in order
02:46to fill that portion of the Layer mask with black, which ends up revealing the eyes.
02:51I'm going to press the M key to switch back to the Rectangular Marquee Tool and
02:54click in order to deselect the image.
02:56One other problem is that his skin tones are a little bit too flashy still;
03:02they don't look as if they've really turned to stone.
03:05So I'm going to take this layer right here and I'm going to press Ctrl+Alt+J or
03:09Command+Option+J on the Mac to create a copy of it, and I'm going to call desat,
03:15because we're going to use it to rob some of the saturation out of the image.
03:18I'll click OK and now let's change the Blend Mode from Overlay to Color, for
03:24starters, just to get a sense of what that looks like.
03:26These would be the actual colors from the stone, blended in with the skin.
03:31To me, that looks pretty good, but it doesn't look exactly right, not quite
03:35what I'm looking for.
03:36So I ended up switching to a mode, I have to say, almost never use, but saturation.
03:42And that went ahead match the saturation of the skin tones with the colors
03:47that we're already finding inside the face and it ends up creating this really
03:51cool like in effect all over the contours of his forehead and his nose and his lips as well.
03:58I just love the fact here that in some places his lips are kind of pink and then
04:02he has these mysterious gray spots as if he was actually turning to stone.
04:09And then the final thing I did was click on the stone layer and then press the 8
04:13key to reduce the Opacity value to 80%.
04:17Bearing in mind by the way that Overlay is not one of the members of the Fill
04:21Opacity 8 group, so it doesn't matter if we change the Opacity or the Fill
04:25value, we'll get the same effect.
04:27And now I'll go ahead and switch to the Full Screen mode.
04:29That's Ctrl+0 in order to zoom out, zoom back in a little bit.

7. The Inversion and Cancelation Modes
Difference, Exclusion, Subtract, and Divide
00:00In this exercise I will introduce you to the two Inversion modes, Difference and
00:04Exclusion, as well as the two Cancellation modes, Subtract and Divide.
00:09I am working inside of familiar looking file called Leaf demo.psd found inside
00:14the 07_inversion folder.
00:16In addition to the leaves in the background, I have got this full width gradient
00:19layer in the foreground, I am going to go ahead and click on it to select it.
00:23And then, let's switch it to the first of the modes, which is Difference.
00:28Now what happens with difference is that anything that's black in the
00:31active layer, does not invert the layers below at all, and anything that's
00:35white, inverts absolutely.
00:38And so we end up with this gradient inversion with the gray values in-between
00:43inverting to different degrees.
00:45Now the great thing about difference, vis -?-vis, the other modes in this set, is
00:49that it's the final member of the Fill Opacity eight.
00:52So notice if I press the 5 key to reduce the opacity of his layer to 50%, we end
00:57up getting a pretty rotten effect here.
01:00So I will go ahead and press 0 in order to reset the Opacity to 100% and then I
01:06will press Shift+5 to reduce the Fill Opacity value to 50% and you can see that
01:11we get a completely different effect.
01:14All right, I am going to press Shift+ 0 in order to restore fill to 100%.
01:19Now let's check out the next mode which is Exclusion, I will press Shift++, in
01:24order to advance to that mode.
01:26Black still does not invert, as you see over here on the left hand side.
01:30White inverts absolutely, as you can see on the right hand side, but the gray
01:34values end up muddying up the image and looking more or less opaque.
01:39Now I have to say, whereas the Difference mode is extremely useful, the
01:44Exclusion mode is more of a special effect that you may or may not find yourself applying.
01:50Just to give you a sense here, I am going to turnoff that gradient layer for a
01:53moment and I am going to turn on this dummy layer and click on it.
01:57And this is just a blank brightness contrast adjustment layer, it's not doing anything.
02:02But, whereas here I had to change the Blend Mode to Difference, which I can do
02:05from the keyboard, by pressing Shift +Alt+E or Shift+Option+E on a Mac.
02:09Notice that the image ends up completely canceling itself out and while that
02:14might not seem like such a great thing, it's extremely useful as we'll see
02:19starting in the next exercise.
02:20Whereas, if I press Shift++ to advance to the Exclusion Mode, we end up getting
02:26all kinds of colorful interactions.
02:29With the red leaves basically remaining intact and the yellowish leaves
02:34inverting to become blue and green and cyan, and so forth, so just to give you a
02:40sense of how these modes behave.
02:42All right, I am going to go ahead and turn off that dummy layer, turn on the
02:45Gradient layer once again and click on it.
02:47And now I will advance to the next mode by pressing Shift++, which is Subtract.
02:53And when you are subtracting black from an image, it ends up doing nothing,
02:57so you can see over here on the left-hand side the luminance levels of leaves are fairly intact.
03:03When you subtract white however, you end up subtracting the brightest luminance
03:07level there is, and so everything ends up conversely going to black.
03:13I what you do know subtract and divide have some problems where
03:17straightforward compositing is concerned because they are beat by some other
03:22modes that we've already seen.
03:23I am going to switchover to this file that's called For comparison.psd and I am
03:29going to turn onto its gradient, it's the exact same gradient we saw a moment
03:32ago, the exact same leaves as well, and I am switch to the Darken blend mode
03:37that employs some traction, which is Linear Burn.
03:40And notice this time we end up with blackness over here on the left hand side
03:45and unmodified leaves over on the right hand side.
03:48And I will press the Escape key to deactivate the Blend Mode for a moment, if
03:52I were to take that layer and invert it by pressing Ctrl+I or Command+I on the Mac.
03:57Now I will switch back to the other image where that gradient is affected by the
04:01Subtract mode and you can see that we end up achieving exactly the same effect.
04:06Here is subtract, and here is that same layer inverted, set to Linear Burn.
04:13The big difference is that Linear Burn is part of the Fill Opacity eight, so if
04:18I press Shift+5 in order to reduce the Fill value to 50%, we end up getting a
04:23more gradual darkening effect over here in right hand side.
04:27If I switch back to Leaf demo file where I've applied the Subtract mode and I
04:31press Shift+5, we get a completely different effect, and that's because Fill and
04:37Opacity affect the Subtract mode in exactly the same way.
04:41So there's really no advantage to using the Subtract mode when you already have
04:46the Linear Burn mode at your disposal and it's a more powerful Blend Mode.
04:50All right I am going to press Shift+0 to increase the Fill value back to 100%
04:55and I'm going to advance to the second cancellation mode, which is Divide.
05:00Notice this time we are ending up clipping the left-hand portion of the image to white.
05:05And those of you who are stuck with me for Chapter 2, you may recall that just
05:10as multiplying luminous levels darkens them, Divide ends up brightening them.
05:15However, whereas Multiply does not clip colors, the Divide mode does, and
05:19especially when we are dividing by the darker colors.
05:22We end up dividing by these very small numbers, and so things brighten up
05:26tremendously, and of course, when you divide by Black which is zero, you get an
05:31undefined number, and that just goes to the roof.
05:34So we end up with this effect here.
05:36Again, Divide is already taking care of by one of the Lighten modes.
05:42And let me show you what that looks like.
05:43I will go ahead and switch back to this Comparative file, and I will restore the
05:47Fill value to 100% by pressing Shift+0.
05:50Now if I press Shift+Alt+N or Shift+ Option+N on the Mac you may recall we are
05:55working with an inverted version of the gradient.
05:58So it's already inverted.
05:59Now if I go ahead and switch to this Inverted gradient to color dodge, switch
06:04back to the other file, and you can see that Divide is exactly the same as
06:10inverting the active layer and applying color dodge.
06:13Once again though, color dodge is part of the Fill Opacity eight, so if I press
06:18Shift+5 to reduce the Fill value to 50 %, I am going to restore a lot of the
06:23detail on the left-hand side of this image.
06:25If I switchover to Leaf demo file, where I've apply Divide to this opposite
06:30gradient, and I press Shift+5 to reduce the Fill value, we end up with this
06:35fairly hideous effect here.
06:38And again, that's because Divide is not part of the Fill Opacity eight, so both
06:41the Fill and Opacity value is affected in exactly the same way.
06:47So again, Subtract and Divide are already taking care of by Linear Burn and
06:52Color Dodge respectively, and the job is done better by those Blend Modes.
06:57Meanwhile, Exclusion is kind of a weird freaky mode, Difference is the mode
07:02that's truly useful, and I'll show you why in the next exercise.

Comparing seemingly identical images
00:00One of the great uses for the Difference mode is that it allows you to compare
00:04seemingly identical images and discover their differences.
00:08And here's how that works.
00:10We are looking at a photo from Fotolia image library, I absolutely love it
00:14because it's a great demonstration of Blend Modes, we have got this photograph
00:17in the background, then this falling type in the foreground set to the Screen
00:21mode I would imagine, in order to create this bright interaction.
00:25The name of the file is Access codes. tiff so I save the image to the tiff file
00:30format, I use LZW compression, which is entirely lossless.
00:35So it doesn't change a single pixel inside the image.
00:38Meanwhile, next-door, it looks like the same image;
00:42we will see that it's not in a moment.
00:43It's called Heavily compressed.jpg, and what I did was, I save that same file to
00:49the JPEG format, and I applied the lowest quality setting possible, which is 0.
00:54And as a result, if you go and zoom in on this image, you can see that we have
00:59all kinds of compression artifacts, they show up as these 8x8 pixel squares, and
01:05basically all of the pixels are rewritten, based on the color of the top left
01:11pixel and that's how JPEG works.
01:14Now let's say we want to get a sense of what exactly has change between these two images.
01:19Well, I am going to right click inside this image and choose Duplicate Layer and
01:24then send it over to Access codes.tiff and change its name to let's say JPEG
01:30version and click OK.
01:32And now we'll switch back to the image at hand.
01:35To compare the two, I will go ahead and change the Blend Mode from Normal to Difference.
01:41Now first it's going to look like the image is gone completely black, so there
01:46must not be any differences between the pixels, because identical pixels set to
01:50the Difference mode cancel each other out.
01:53However, that's not actually the case.
01:55So what I am going to do is press the Escape key to deactivate the Blend mode there.
02:00And I'm going to create a Merged version of these two layers by pressing
02:05Ctrl+Shift+Alt+E or Command+ Shift+Option+E on the Mac.
02:09We will go ahead and create a merged composite on a new layer.
02:13I will go ahead and call this new layer Merged as well.
02:17Now what you need to do is go up to the Image menu, choose the Adjustments
02:20command and choose Levels or you can press Ctrl+L, Command+L on the Mac and
02:25look at that histogram, there is some action going on in the very dark regions of this layer.
02:32To make it evident, go ahead and grab that white slider triangle and move it
02:38very far over to the left hand side.
02:41And I am going to ultimately settle on a white point value of 20.
02:45So that we have a fair amount of distinction going on here and then I will click OK.
02:50Any pixel at this point that does not appear black has been rewritten, which
02:56means that applying a lot of JPEG compression in our case, has rewritten just
03:01about every single pixel in the image.
03:05So any time you want to be able to compare two seemingly identical images and
03:10figure out if they are truly the same thing, then you can do this exact same
03:15tests we did here, using the Difference Blend Mode, going ahead in merging the
03:20two layers and then using the Levels command to exaggerate the differences.

Creating type that inverts any background
00:00In this exercise I will show you how to use the Difference Mode to create live
00:04editable text that inverts anything behind it, and this works for Line Art as
00:08well, anything that's white against the black background or just plain white and
00:13it's really a great trick.
00:16I'm working inside a file called Double model comp.psd, it's found inside the
00:2007_inversion folder.
00:23And it's so called by the way, because I have two versions of this model,
00:26currently we are seeing the model 1 layer, but if I turn on the model 2 layer,
00:31you can see we've got another shot of the same model far in the foreground and
00:35she's covering up the background image, because she has this white background.
00:38That's rude in everything, but it's not a problem at all, and we can test that
00:42that background is white, by selecting a Magic Wand tool making sure that the
00:47Tolerance values is set to 0, Anti- alias is off, Contiguous is turned on,
00:52problem is that I have the wrong layer selected.
00:54So I will go ahead and click on model 2, and now I'll click in the background
00:58and you can see that we've got this huge area of white.
01:02And if I want to test that it's white, then I press the I key switch to the
01:06eyedropper and just go ahead and click some place inside that background, test
01:11the color up here in the Color panel, sure enough we've got white, because the
01:15Saturation value is set to 0 and the Brightness value is set to 100%.
01:20So let's make that white disappear, not by masking of course, press Ctrl+D or
01:24Command+D on Mac to deselect the image.
01:26All we need to do is press Shift+Alt+M or Shift+Option+M on the Mac to switch to
01:31the Multiply mode, and that white background disappears.
01:35So that's step one.
01:36Step two is to integrate the text.
01:38So I am going to go ahead and turn that text layer on.
01:41and then click on it to make it active.
01:43Now I've rasterized this text, because I was using a few fonts that are on my system.
01:48probably aren't on yours.
01:49But this trick would work just as well for live editable text.
01:53Now I am going to press the D key in order to reinstate the default colors of
01:57black-and-white, and I will press the M key to switch back to the Rectangle
02:01Marquee tool and then I am going to fill this text with white by pressing
02:06Ctrl+Shift+Backspace, that would be Command+Shift+Delete on the Mac.
02:11The ideas is that Ctrl+Backspace or Command+Delete goes ahead and fills the
02:15layer with the background color, because we have the Shift key down as well,
02:19irrespective of the transparency, so the letters remain intact.
02:23The great thing you may recall about the Difference mode is that anything that's
02:28white on the active layer, inverts entirely.
02:32So it automatically inverts anything behind it, which means that we can change
02:36the mode from Normal to difference to achieve this effect right here.
02:41And now if I press the Ctrl key or the Command key on the Mac to get the Move
02:45tool on the fly and drag this text elsewhere inside the image, it is going to
02:50continuously invert everything behind it.
02:53And as I say, this works with live editable text, so you can turn around and
02:57edit the text anytime you like.
02:59It also works with Line Art as long as a Line Art is white, against the black background.
03:04All right, I am going to press Ctrl+Z or Command+Z on the Mac, to undo that movement.
03:08We do have what I consider to be an aesthetic problem however, even though I
03:13like the fact that we have this black text against the white background, I
03:16don't want the text that overlaps the models to turn blue, because its
03:20inverting those warm skin tones.
03:22Instead, I'd like those areas of the text to turn white, and I'll show you how
03:26to make that happen in the next exercise.

Making inversion type black and white
00:00I've saved my progress as Self- inverting type.psd found inside the
00:0407_inversion folder.
00:06In this exercise I'm going to show you how to create inverting type that's
00:10either black or white, so that we have a high contrast effect with a little
00:15bit of gray action in between and it's ultimately a function of adding on some
00:20adjustment layers, but it also involves a special advance blending trick as well.
00:25So the first thing that we're going to do with the text layer active is press
00:29the Alt key or the Option key on the Mac, click on the black/white icon and go
00:33ahead and choose the Vibrance command and I'm going to call this layer desat
00:39and very importantly turn on Use Previous Layer to Create Clipping Mask and click OK.
00:45Next I'm going reduce that saturation value to its absolute minimum which is -100.
00:50Now I'm losing the minus sign here on the PC, but I have reduces the
00:55saturation to its absolute minimum, you can see the slider triangle is all the
00:59way to left and yet inexplicably I'm not seeing any difference where the text
01:06is concerned, it's still blue.
01:08So how is that I remove all the saturation and I don't get gray, let me show you.
01:13I'm going to go ahead and collapse the Adjustments layer for a moment and I'm
01:16going to Alt click or Option click on that horizontal line between the
01:21adjustment layer and the text and you can see as soon as I unclip the layer the
01:25entire image turns gray.
01:27So obviously the adjustment layer is working it's just not working properly.
01:32I'm going to press Ctrl+Z or Command+Z on a Mac to re-clip that layer, here is
01:36what we have to do, you got to go down to the text layer which is the layer
01:40that's doing the clipping and then double-click on an empty portion of that
01:44layer, to bring up the Layer Style dialog box and here is our problem.
01:49Notice this checkbox that says Blend Clipped Layers as Group.
01:53So what's happening here is the adjustment layer is de-saturating the layer
01:58and then Photoshop is turning around and applying the difference mode, do you
02:02see how that's a problem the layer was already de-saturated it was white, so
02:06it had those saturation associated with it in the first place, so we're still
02:10getting the same effect.
02:11However as soon as you turn that checkbox off you reverse the order of the operations.
02:16Now Photoshop is applying the difference mode to that white text first and then
02:21it's turning around and de -saturating the results.
02:24So remember if these kinds of things don't go well for you, you've got these
02:28two checkboxes right here that you can turn on and off in order to achieve different effects.
02:34Alright now I'll click OK in order to accept that modification, I'm going to
02:38click on the desat layer now to select it and then I'll press the Alt key or the
02:42Option key on the Mac click the black/ white icon and choose the Levels Command,
02:47because we still need to make those gray areas of the text white, and I'll go
02:51ahead and call this layer B&W and I'll turn on that checkbox once again very
02:56important to our role end up affecting the entire composite image.
03:00And now inside the Adjustments panel I'm going to drag that white slider
03:04triangle over to the left and you can see how we are making what were formerly
03:10gray portions of letters white.
03:13Now I've got a little too far with this Y point value, so I'm going to take it
03:16up to 110 that's all there is to it.
03:19Now I'll go ahead and hide the Adjustments panel, so we have a little more room to work.
03:22Switch back to the text layer and once again if I Ctrl+Drag or Command+Drag that
03:27text, it inverts every thing behind it successfully and we even get these nice
03:32transitions here between the black and the white areas of the letters.
03:37If I go ahead and press Ctrl+Z or Command +Z on the Mac to Undo that movement, we
03:41have our text back where it belongs and I just want to zoom in here, so you can
03:44see what I'm talking about, we do have some transitional grays left over.
03:48So it's a high contrast effect with a little bit of softness automatically built into it.
03:54Now let's go ahead and switch to the full screen mode and zoom in on our final
03:59composition and there you have it a couple of different ways to take advantage
04:03of one of the best blend modes in Photoshop Difference.

8. The Component (HSL) Modes
Luminosity, Color, Hue, and Saturation
00:00In this exercise we'll take a look at the component modes which are HSL modes
00:05that is to say Hue, Saturation and Luminosity as well as Color.
00:09We'll start by looking at Luminosity and color, because they're the easiest to
00:13understand and their applications are the most obvious as well and then we'll
00:17take a look at Hue and Saturation.
00:20I'm working inside a file called the Assyrian and sea.psd, found inside the
00:2508_component folder.
00:26I've got the Assyrian layers selected, notice that that's these statues that
00:31we're seeing inside the Image window.
00:32If you turn it off for a moment you'll see the sea in the background.
00:36So let's say we want to merge these two images together we want to keep the
00:39color of the sea and we want all the details associated with the Assyrian.
00:44All you need to do in that case is switch from the very first mode Normal to the
00:49very last mode Luminosity and that's going to go ahead and merge the detail from
00:55the Assyrian layer with the colors from the layer or layers in the background.
01:00And the reason is because we're keeping his luminance levels, so we're totally
01:04abandoning the color values associated with this Assyrian carving and we're
01:09replacing it with all the color information in the background.
01:12Now let's say you want to do the opposite, you want to take the sea layer and
01:16you want to merge its color with the detail from the Assyrian, which will give
01:20us the same effect of course, but if the sea layer were in front then you would
01:25choose the commuted version of luminosity.
01:29Remember I was telling you couple of chapters ago that Overlay and Hard Light
01:33commuted versions of each other well the same goes for color and luminosity.
01:37If I wanted to replace the colors of the Assyrian with the sea layer in front,
01:41then I would go ahead and choose the Color mode.
01:44Those are your too big HSL mode, they are the once that you're going to use in a regular basis.
01:49If you want to divide color into its component parts then you could try
01:53choosing Hue or Saturation.
01:55So if I chose Hue and applied it to the sea layer than I would apply all the
02:00Hue values that is the various blues and greens from the sea layer with the
02:04saturation levels and the luminance levels of the Assyrian here on the background.
02:10Which means that we immediately as you can see here lose saturation, because
02:15they're carving wasn't very saturating the first place.
02:18So if I press Ctrl+Z or Command+Z on the Mac to Undo that change and returned to
02:23the color mode, you can see that we have higher saturation values now.
02:26If I press Ctrl+Z or Command+Z again we see lower saturation's associate with Hue.
02:32It turns out Hue is actually really great mode;
02:34I'll show you a wonderful use for in the later exercise.
02:37The other one that you can try out is saturation.
02:40Now I already showed you an application of saturation at the end of the previous
02:44chapter, but just to review things here.
02:47If you choose Saturation you'll keep the saturation values from the sea layer
02:51and mix them in with his Hue and luminance levels of the Assyrians, so the
02:56Assyrian is now restored to its former orange.
03:00However it's a higher saturation orange.
03:02Notice this if I turn off the sea layer for a moment before he was pretty dull
03:07little bit brownish looking, as soon as I turn the sea layer back on, because
03:11the sea layer is more highly saturated we end up lifting the saturation values
03:16from the Assyrian in the background.
03:19In the next exercise we'll use one of these modes specifically color in order to
03:23transform this ancient Assyrian carving into those wildly colorful composition.

Colorizing artwork with layers
00:00In this exercise I am going to show you how to colorize a photograph or a piece
00:04of artwork using independent layers combined with the Color Mode.
00:08We'll start things off inside the file Assyrian & sea.psd found inside the
00:1208_component folder.
00:13I am going to make a copy of this Assyrian layer by pressing Ctrl+J or Command+J
00:18on the Mac and then I'll turn it off for a moment.
00:21Return to the original Assyrian layer and let's go ahead and switch it to that
00:25ultimate contrast mode which is Linear Light, by selecting Linear Light here
00:31from the Blend Mode pop-up menu, and that goes ahead and integrates the texture
00:35of the background and the foreground for that matter with the photograph of the
00:38sea, but it's a little too much I think.
00:40So I am going to press the Escape key to deactivate the Blend Mode here on the
00:44PC and then I'll press Shift+33 in order to change the Fill value to 33%.
00:51Now let's turn on the original Assyrian layer because I want to reinstate him.
00:55If you switch over to the Channels Panel, you will see that I have created three
00:59alpha channels in advance for you;
01:01one that selects the entire guy, another that just selects the eye, and then
01:06finally one that selects the hair.
01:08You note that the masks are pretty rough, frankly.
01:11I created all of them because we don't really have that much to work with here
01:16in the way of color detail or anything like that.
01:19When you are selecting something along the lines of the monochrome carving,
01:22you're pretty much at the disposal of the Selection tools.
01:26So I ended up working with of all tools, the Quick Selection Tool, actually
01:30it worked pretty well for this, as well as the Elliptical Marquee and the Lasso Tool.
01:35Anyway, I'm going to go ahead and load up the big guy channel by Ctrl+Clicking
01:39or Command+Clicking on it.
01:41Then I'll switch back over to the Layers Panel, and with that top Assyrian layer
01:45selected, I will drop down to the Add Layer Mask icon and click on it.
01:50Now we've got the carving set against the sea, but I want to give him let's say
01:53a little bit of color and I'm going to draw that color from this brown layer
01:57right here, but if I just colorize him with a flat shade of brown like this,
02:01he's going to look pretty darn flat.
02:03So I wanted to introduce some variation, and here is how I went about that.
02:08First, I pressed Ctrl+J or Command+J on the Mac in order to create a copy
02:12of that brown layer.
02:13Turn it off, we'll come back to it in a moment.
02:15Select the original brown layer.
02:17Then press the D key just to make sure your foreground and background colors are
02:21at their defaults, black and white.
02:23Then go up to the Filter menu, choose Render and notice in addition to Clouds,
02:28you have Difference Clouds.
02:30Clouds in case you don't know, applies a random fractal noise pattern that
02:34happens to look something like clouds I suppose, and this is the kind of effect you get.
02:39Every time you'll apply the filter, you get something different.
02:42I am going to press Ctrl+Z or Command+Z on the Mac to undo that change.
02:45Just below the Clouds Filter is a filter called Difference Clouds and what it
02:49does is it applies the Clouds Filter once again randomly, subject to the
02:54Difference Blend Mode.
02:55So it goes ahead and blends the Clouds with the current color that's brown,
03:00using that same Difference Mode that we saw on the previous chapter.
03:03So I'll go ahead and choose the command and we end up getting this effect here.
03:07Your results may vary.
03:08And then if I press Ctrl+F or Command +F on the Mac to repeat the filter,
03:13we apply Difference Clouds again and that goes ahead and reinverts the color pattern.
03:18I'll press Ctrl+Z or Command+Z on the Mac.
03:21We change the image to predominately blue because any place where white was
03:26assigned, in the fractal noise pattern, we ended up inverting the brown and
03:31that changed it to blue.
03:32If I press Ctrl+F or Command+F to repeat the filter, we reinvert all over the
03:37place and we're introducing all kinds of new colors.
03:40Now you can keep doing that over- and-over again, if you like, but two
03:43applications of Difference Clouds is enough to get the result we're looking for.
03:47I'm now going to turn the original brown layer back on and I am going to reduce
03:51its Opacity value to 70% by pressing the 7 key.
03:55Then, I'm going to merge these two layers together by either going up to the
03:59Layer Menu and choosing the Merge Down command or you can just press Ctrl+E
04:03or Command+E on the Mac and that goes ahead and gives us this sort of
04:07variable brown color.
04:10Now I am going to press the Alt key or the Option key on the Mac and click that
04:13horizontal line between brown and the layer below, so that we're clipping the
04:17brown inside of that Assyrian layer.
04:20Now I am going to return to the Channels Panel, lift that eye channel right
04:25there by Ctrl+Clicking on it or Command +Clicking on it on the Mac, return to
04:29the Layers Panel and dropdown to the Add Layer Mask icon and Alt+Click or
04:34Option+Click on it.
04:36That way we're masking away the eye.
04:38I am going to press Shift+Alt+C or Shift+Option+C on the Mac to switch this
04:43layer to the Color Mode and that goes ahead and colorizes this entire guy
04:48with the exception of his eye, that's the only thing that's not getting colorized here.
04:53Alright now I want to colorize his hair using this rainbow layer that I created,
04:58using the Gradient Tool of course, and I'm going to go ahead and click on it to
05:02select it and then I'll go up to the Channels Panel and let's load the hair
05:06channel by Ctrl+Clicking on it or Command +Clicking on it on the Mac, switch back
05:11to the Layers Panel, dropdown to the Add Layer Mask icon and click on it in
05:16order to mask that crazy gradient inside of his hair.
05:20Now of course we want to colorize the image using that layer, so press
05:25Shift+Alt+C or Shift+Option+C on the Mac to once again switch to the Color Mode.
05:29So notice how that works by the way.
05:31If I turn that layer off, we had already colorized that area using the layer
05:36below, that doesn't matter.
05:38You can colorize over-and-over again.
05:40You can heap all kinds of color layers on top of each other because they're all
05:44burning through essentially to the original luminance data and so each layer of
05:48color ends up replacing the one below.
05:51At this point I felt like the composition would benefit if his eye was brighter.
05:55I start off by going over to the Channels Panel and loading that eye channel
05:59once again by Ctrl+Clicking on it or Command+Clicking on the Mac and then switch
06:04back to the Layers Panel, drop down to the black/white icon, press the Alt or
06:07Option key and click on it and then choose Brightness/Contrast.
06:13I was originally thinking this was going to work as a dummy layer so I just
06:16called it dummy and then clicked OK.
06:18I'll go ahead and collapse the Color Panel for a moment here and expand
06:22the Layers Panel and then I changed this layer to the Screen Mode in order
06:27to brighten up that eye, but that didn't end up giving me the brightness I was looking for.
06:31So I went ahead and changed the values associated with the adjustment itself.
06:35I took the Brightness value up to 50 and I took the Contrast value up to 100.
06:40So you can add values along with blend modes to your adjustment layers to create
06:45a higher impact effect if you want to.
06:47Now I am going to collapse the Adjustments Panel.
06:50Notice that my Layer Mask is still selected.
06:52I am going to switch over to the Brush Tool and then I'll right-click inside the Image Window.
06:56Notice my Size is 90 pixels, my Hardness is 0%, my foreground color is black, so
07:02what I am going to do here is paint away the shading below the eye like so, just
07:07along the bottom eyelid and that's it and that is the final effect.
07:11I'll go ahead and press the F key a couple of times and zoom in.
07:14That is one way anyway to colorize a photograph or a piece of artwork, if you
07:19like, using the Color Blend Mode here inside Photoshop.

Correcting skin tones with Hue
00:00In this exercise I'll show you how to correct color modeled skin tones using the Hue Mode.
00:06I am working inside of a file that's called Average hue.tif.
00:09It's found inside the 08_component folder.
00:12This is a photograph that I shot of my son Max.
00:16You can see how his skin tones waver from oranges and pinks into this sort of
00:21yellow region up here, and in this particular case, it's because the camera
00:26misread the actual colors.
00:29However, you might run into situations where you're looking at a person who has
00:33modeled skin tones and you want to correct for them and here's how.
00:37First thing you want to do is mask the subject of your image and in the case of
00:41this photo, it's pretty easy.
00:43I am going to switch over to the Channels Panel here.
00:45Notice that I've created a mask in advance, but we are going to create it
00:49together using a slightly different technique than we had in the past.
00:53If you take a look at the independent color channels, you will see that we don't
00:56have much contrast going on where Max's face is concerned, in the Blue channel.
01:00We have an awful lot of weirdness going on in the Green channel, that's part of
01:05the reason that we're having the color modeling in the first place is there is
01:07so much variation inside of his face.
01:10And then if you switch over to the Red channel, you'll notice that his face
01:14is incredibly bright inside of this channel, another reason we're having the problem.
01:18I am going to go ahead and make a copy of that Red channel because that is
01:23where we have the most contrast and I'll just go ahead and rename it mask, and
01:27then we need to enhance the contrast of the image, but instead of doing so
01:30using the Levels command, I am going to use Curves instead which will give me a
01:34little bit more control.
01:35So I am going to choose Image> Adjustments>Curves or you can press Ctrl+M or
01:40Command+M on the Mac in order to bring up the Curves dialog box.
01:43Now if you are working along with me, you want to click on this double-pointing
01:47arrowhead right there to make sure you can see your Curve Display Options and
01:51make sure Show Amount of is set to Light as opposed to Pigment.
01:55Then, go ahead and take that bottom left point and drag it over to the right
02:01until the Input value changes to 64.
02:04Now if you miss the mark a little bit, you can dial-in and input 64 or you can
02:08also nudge the point from the keyboard.
02:10So I've pressed the Left Arrow key a couple of times in order to nudge it back to 64.
02:15So Output should be 0, Input 64.
02:18Then go ahead and click somewhere along this line in order to set a point.
02:22What we are looking for this time around, I am going to press Shift+Left Arrow a few times here.
02:28I'm ultimately looking for the Input value to be 115 and then the Output value
02:34needs to be 140 and by the way we are talking at luminance levels here.
02:39So we are remapping what was formerly a luminance level of 115 to 1 of 140.
02:44So we're brightening the center of that curve.
02:47So we are starting off by clipping a ton of dark colors to black and then we are
02:52brightening the mid-tones.
02:54Once your curve looks like mine, go ahead and click OK in order to accept the results.
02:59Now we are just getting us Lasso Tool to more or less encompass Max's face.
03:03So I am going to press and hold the Alt key or the Option key on the Mac and
03:06click along here and I am keeping that Option or Alt key down, so that I can
03:11take advantage of the polygonal Lasso Tool here and I'm going to dip close to his ear.
03:15Notice as usual I am not getting right next to the stuff I want to keep, I am
03:20trying to stay inside of this, sort of black alley here.
03:24This area right there underneath his chin is a little bit of neck showing up and
03:29then we have some neck down here toward the top of the zipper area, so go ahead
03:33and select around there and then finally complete the selection like so.
03:39Then, you go up to the Select Menu and choose the Inverse command so that we're
03:43selecting the background instead of his face.
03:45My foreground color happens to be black, so I am going to press Alt+Backspace or
03:48Option+Delete on the Mac to fill that selected region with black, and then press
03:53Ctrl+D or Command+D on the Mac to deselect the image.
03:56Now we have managed to mostly select all the skin details, but we have
03:59selected more than that, I've selected into his teeth for example and into his eyebrows as well.
04:04Not a concern.
04:05Let's just go ahead and load at this mask by Ctrl+Clicking or Command+Clicking
04:10on it, they are in the Channels Panel.
04:11Then I'll switch back to the RGB image, switch over to the Layers Panel.
04:16I am going to convert Max to a Smart Object and the reason I am doing this is
04:20because we're going to be applying this mask as a Filter Mask in just a moment
04:26and we need a Smart Filter to pull that off.
04:28So go up to the fly-out menu, choose Convert to Smart Object.
04:32Then we might as well go ahead and rename this layer Max.
04:35I'll go up to the Filter Menu, choose Blur and choose a command that you've
04:39probably never used in your life, it's Average, and what it does is it finds the
04:44one and only average color in the entire image and it goes ahead and fills the
04:50entire image with it, like so.
04:52So notice because we had a selection active, it just went ahead and filled
04:56up Max's face, but we've changed his entire face to this weird sort of
05:01brownish gray color.
05:02That's exactly it turns out what we want.
05:05However, we need to change the Blend Mode for the Filter.
05:08So double click on the Slider icon to bring up the Blending Options dialog box.
05:13Initially, I expected the Color Mode was going to do the job for me, but
05:17notice what happens, we ended up creating this sort of gray flesh, that's not
05:21what we're looking for.
05:22I switch to Hue instead which is the way I suggest you work as well.
05:26If Color doesn't give you the desired results, see if Hue might do you better,
05:30and as soon as I chose Hue, notice that, completely fixes the image.
05:35It's amazing, and then I went ahead and reduced the Opacity value to 70%, click OK.
05:40And so just to give you an idea of what kind of difference is made, this is the
05:44original image with all those weird sort of yellows and pinks competing for
05:48attention there and this is the filtered version of the image.
05:52Not only do the flesh tones improved dramatically, but his teeth remain nice and
05:57white because they are low saturation teeth in the first place.
06:00Thanks to the Hue Blend Mode here inside Photoshop.

9. The Luminance Sliders
Using the This Layer slider option
00:00In this exercise, I am going to introduce you to your final blending
00:03option inside Photoshop.
00:05And these are the luminance exclusion slider bars, which allow you to either
00:09drop away specific ranges of luminance levels inside the active layer or force
00:14the display of luminance levels from the underlying layers.
00:18We are going to use these options in order to mass this lightning into these clouds.
00:23So the lighting actually appears to be coming out of the clouds, as if it's
00:26all one organic image.
00:29Now I have two files open, one is called Big cloud.jpg and the other one is
00:32called Lightning.jpg.
00:34They are both found inside the 09_sliders folder.
00:37You might look at this lightning and figure if you were actually given this job,
00:41my gosh this is going to be so complicated.
00:43We have all these tiny little tendrils of light coming off here.
00:46Actually masking bright lightning against a dark background is quite easy.
00:51All you have to do is go over to the Channels Panel and find the channel that
00:55offers the most contrast, you'd see that the Red Channel doesn't offer enough,
00:58the Blue Channel is kind of a mess, it's got all kinds of posterization inside
01:02of it particularly over here on the left hand side.
01:04The Green Channels probably the best bet.
01:07Even though, it's not in great shape either.
01:09But we go ahead and grab that green channel, duplicated by dropping it onto the
01:13little page icon there at the bottom of the panel.
01:15Presumably, we would rename this mask or something along those lines, press
01:19Ctrl+L or Command+L to bring up the Levels dialog box and go ahead and crank up
01:24the black slider value to about 90 should do us.
01:28And then I take the white slider triangle down to something like 220 and at that's it.
01:33Click OK, we have got ourselves a mask.
01:36Then you would Ctrl+Click or Command+ Click on the mask, in order to load it up
01:39as a selection outline, switch back to the RGB image, switch over to Layers
01:44Panel, double-click on the Background Layer and let's go ahead and call this New
01:48Layer lightning and then click OK.
01:51Just drop-down to the Add Layer mask icon at the bottom of the Panel and click on it.
01:55And now you have managed to mask the lightning.
01:58Let's go ahead and copy it over to the clouds image by right-clicking inside the
02:01image window, choosing the Duplicate Layer command and then I'll go and switch
02:05the Document to Big clouds.
02:07The layer is already named so we are good to go, click OK, switch over to that
02:11image and we've got ourselves a mass lightning.
02:14But couple of different problems, one is, we've got these sort of dark edges
02:18surrounding each one of the bolt of lightning.
02:21And the lighting doesn't appear to be coming out of the clouds.
02:24It just appears to be sitting on top of them.
02:27By the way, this is taken too much effort.
02:29Even though, I went that quickly we could do this job a lot better with a lot
02:34less work without any masking whatsoever, just by taking advantage of blending.
02:39So I'm going to right-click on that Layer Mask and choose Delete Layer Mask to get rid of it.
02:45The first step where blending is concerned, is to keep the bright stuff drop
02:49out the dark stuff, so of course we are going to switch to a lighten mode and
02:53our pre-eminent lighten mode is Screen, and that's going to work pretty darn well for us.
02:57That does a lot of the work right there by itself, without harming the image or
03:01requiring us to generate a mask.
03:03However, we can still see an awful lot of that red background and it's
03:08brightening of the clouds as well.
03:10So we need to drop out that background.
03:13And you do that by bringing up the Blending Options dialog box.
03:16And the easiest way to bring up the dialog box is just double-click on the
03:20thumbnail, in the case of a pixel-based layer like this one.
03:23If you're working with the some other kind of layer you can double-click any
03:26empty portion of the layer over here on the right-hand side or you could just
03:29drop-down to the fx icon and choose Blending Options.
03:32Any of those approaches is going to work.
03:35And then notice these sliders down here at the bottom of the dialog box, they
03:39are often called the Blend If sliders.
03:41Blend If refers just to this little blending option right here and I'll show you
03:45what's up with that in the future exercise.
03:48But the sliders function independently of that option.
03:52They are that This Layer slider and the Underlying Layer slider.
03:55This layer controls which luminance levels are visible in the active layer,
04:00Underlying Layer which should be called underlying layers plural because it
04:04could be a stack of layers piled on top of each other, controls the display of
04:09luminance levels being forced through from those underlying layers.
04:12So we are going to start things off by dragging this white slider triangle over to the right.
04:18And notice what I'm doing here.
04:19As soon as I take it over to let say something like well let's say a 101 that's fine.
04:24Any luminance level that's a 101 or brighter, bearing in mind that 0 is
04:29black and 255 is white.
04:30Anything with the luminance level of a 101 or brighter, is going to go transparent.
04:35So it's a dropping out and anything a 101 or darker, is remaining visible.
04:40That's exactly the opposite of the effect we want of course because we are
04:44dropping away the bright stuff the lightning and we are leaving the dark stuff in its wake.
04:49So let's go ahead and reset that guy all the way back to 255 and instead we will
04:54drag the black slider triangle like so.
04:57And I'm going to take it over to let's say 85 for now.
05:01And at this point I am saying, anything that has a luminance level of 85 or
05:04darker, drop that out of the active layer.
05:07Anything 85 and brighter, keep that visible.
05:11Problem is let's go ahead and zoom in here so you can see, we've got some
05:15oftenly jagged transitions.
05:17That's because, this is an on-off proposition so far.
05:19Either the pixels are opaque if they are brighter than 85 or transparent if they are darker.
05:25What we need to do here is introduce some fuzziness that is lend some
05:29softness to this transition and if you take a very close look at the slider
05:33triangle's, you will notice that they are different than what we just saw in
05:36the Levels' dialog box.
05:37Instead of being solid triangles, they have a little cleft in the middle of them.
05:41And that shows you that they're actually two triangles fused together.
05:44You can pull them apart by pressing the Alt key or the Option key on a Mac and
05:48dragging in our case, the right half of that slider triangle over to 175 is
05:55what I'm looking for.
05:56And so now, notice that we have these nice soft transitions, around the bolt of lightning.
06:01And what we were saying just to be clear about what these values now mean.
06:04Anything that has a luminance level of 85 or darker is going transparent.
06:09Anything with a luminance level of 175 or brighter is remaining opaque subject
06:15to the Screen Mode of course.
06:16And anything in between 85 and 175 is growing increasingly opaque, so that we
06:23can see it more and more over the span of these luminance levels.
06:27And as a result, we get this nice, soft transition.
06:30Alright, I will go ahead click OK in order to accept that result and that's how
06:35you use that this layer slider, inside of Photoshop.
06:39In the next exercise, I will demonstrate how to work with the underlying layer slider.
Collapse this transcript
Using the Underlying Layer slider option
00:00In this exercise, I'll show you how to force through luminance levels from one
00:04or more underlying layers, using the underlying layer slider bar.
00:08I have saved my progress as Clouds & Lighting.psd, found inside the 09_sliders folder.
00:14We are going to revisit the blending options by double-clicking on an empty
00:17portion of this lighting layer.
00:19Notice by the way, that everything we've done so far is a parametric
00:24nondestructive modification.
00:26In other words, we are using parameters inside of a dialog box in this case, in
00:31order to make our modifications, which means that we can change our mind anytime we like.
00:36I could go ahead and reset every single thing that I've done so far, just by
00:41changing the options here inside the dialog box.
00:44However, I don't want to do that of course.
00:46So I am going to reinstate the settings that were here when I first visited the dialog box.
00:50By pressing the Alt key or the Option key and a Mac, that changes a Cancel
00:54button to Reset button and then you click on it.
00:57And all of our options come back into place.
01:00Even though, the lightning is masked against the clouds.
01:04And it's masked better than it was once with the layer mask.
01:06Notice that we have these nice, soft transitional edges.
01:10The lighting still doesn't appear to be coming out of the clouds.
01:13It appears to be sitting on top of the clouds.
01:14So what I would like to see happen, is that the cloud colors up here at the
01:19top, force through.
01:21If I were to drag the black slider triangle over to the right, you can see that
01:26I would end up masking the lightning inside the clouds.
01:29So I'm forcing through the dark colors from that Underlying Layer and in my
01:33case, I am saying anything with the luminance level of 124 or darker in the
01:37active layer is forcing through.
01:40Anything 124 or lighter, is behaving normally.
01:44That's the opposite of what I want.
01:46So I will go ahead and drag this black slider triangle back over to the left.
01:50And instead, I will take this white slider triangle over to 160s when I'm looking for.
01:56And now, I am saying anything with the luminance level of 160 or brighter is
02:00forcing through and that would be these colors in the clouds here.
02:03Anything 160 or darker is behaving normally.
02:07So that we can see, the lightning covering the darkest portions of the image,
02:11which include these dark blues inside the sky.
02:14Now of course, we have got ourselves another on/off proposition that is either
02:17the pixels are forcing through or they're not.
02:19So we are going to have some jagged transitions.
02:21The solution is to press the Alt key or the Option key and a Mac and drag in
02:26this case, the right half of that white slider triangle until you reach 185.
02:31So we are looking for just a little bit of fuzziness there.
02:35And now we are saying anything with a luminance of 185 or brighter is forcing
02:39through, anything 160 or darker, is behaving normally.
02:43And anything between 160 and 185 is gradually forcing through the lightning layer.
02:50Now we're done.
02:51I will go ahead and click OK in order to accept that result and notice, what a
02:55wonderful job those two sliders have done.
02:58We have got these tiny little tendrils of lightning that are passing in and out of the clouds.
03:03We've got these spot bits of lightning inside the clouds as well, just
03:07beautiful stuff here.
03:09And that's exactly the kind of thing that you can expect from the Luminance
03:12Exclusion slider bars, here inside of Photoshop.

Achieving greater control with Blend If
00:00In this exercise, I am going to show you how to work with that Blend If Option,
00:03that's located just above the slider bars.
00:06What it does is, it allows you to employ the slider bars based on the contents
00:10of specific color channels, which gives you more control over what you're doing,
00:14but it's little hard to wrap your mind around the results.
00:18I will walk you through it here.
00:20The idea let's say, is that I'm pretty happy with what I've been able to achieve
00:25here in this file that I'm now calling Electric storm.psd.
00:29However, I can't did get beyond the fact that we've got these kind of sort of
00:33peach colored halos around each one of the lighting bolts.
00:37It's great that they're nice and fuzzy.
00:39But why are they peach colored?
00:41Except for the fact, they're coming out of kind of a peachy cloud that just
00:44doesn't really make that much sense.
00:46What I prefer to do is create a cleaner effect like this one here, where the
00:51lighting bolts are more colored neutral.
00:53I can do that with a little bit of more work, using that Blend If option.
00:58But we are going to have to start over to do it.
01:00Let's go and return to Electric storm here.
01:02I will zoom back out.
01:03And I am going to right-click on an empty portion of the lighting layer and then
01:06drop-down to this option right there, Clear Layer Style.
01:10If you choose that, you will clear away not only any layer effects that are
01:13applied, but also any of the blending setting.
01:16So I got rid of the screen mode for example and I also reset those slider bar values.
01:22And I am doing this so we can get a sense of what's going on inside these two images.
01:26So I am going to switchover to the Channels Panel.
01:28And you may recall the Red Channel very bright where this lighting is concerned.
01:32The Green channel much darker, but the green channel also has a lot of flair
01:37associated with each one of the bolts of lightning.
01:39If you switch to the Blue channel, you'll notice that even though it's a
01:43pretty clunky channel, it has sharper contrast where the bolts of lightning are concerned.
01:49So that's the channel that we are going to use to blend the image.
01:52Now we are using the contents of that channel, but we are going to be blending
01:56the composite layer.
01:57And you will see what that looks like in a moment.
01:58I am going to switch back to the RGB image, turn off the lighting layer so that
02:02we can check out the Background image.
02:04We need to get a sense of what's going on with it as well because after all it
02:08is the Underlying Layer.
02:09So I am going to switch back to the Channels Panel and if you take a look at the
02:13Blue channel, let's start with the bottom this time.
02:15You will see that we just don't have much contrast going on here at all.
02:19The green channel has a lot better contrast.
02:21The Red channel has an incredible amount of contrast in fact, in fact the cloud
02:26is almost entirely white and the blue behind the cloud is very dark.
02:30What we are going to do we are going to use the Blue channel as our this layer
02:34of control and we will use the Red channel as our Underlying Layer control.
02:39So let's switch back to the Layers Panel, click on the lighting layer to make it
02:42active, turn it on, switch the Blend Mode from Normal to Screen.
02:46And then go ahead and double-click on an empty portion of that layer to bring up
02:50the Layer Style dialog box and then switch to Blend If.
02:53So now normally, it's Gray.
02:56Meaning, it's not turned on at all.
02:58We are not paying attention to specific color channels.
03:01We are just using the Luminance Exclusion slider bars by themselves.
03:04However, if you switch it to a specific channel for example we want Blue where
03:09this layer is concerned, than the slider bars actually turned that color to show
03:13you that you're working from that channel.
03:16Again, you are just using the information in that channel to blend the entire layer.
03:20And now, let's go ahead and drop away the dark colors from that sky, by taking
03:24this black slider triangle for This Layer up to 55 and then press the Alt key
03:30or the Option key on a Mac and drag the right- half of that slider triangle all the way up to 200.
03:38And notice, now that we lose that sort of peach colored fringing, around the
03:42bolts of lightning and we have crisper contrast as well.
03:46Now let's switch Blend If from Blue to Red because after all that's where the
03:51underlying cloud is brightest.
03:53And now I am going to drag the white slider triangle for the Underlying
03:57Layer slider down to 195.
04:00Press the Alt key or the Option key on a Mac and take the right-half of that
04:04white slider up to 230.
04:07And notice by the way, that we have a wider fuzziness range for both Underlying
04:11Layer and for that This Layer slider, that's associated with the blue channel.
04:17Thanks to the fact that we were working from a single channel of information.
04:21And so what that means is two things.
04:23First of all we have better control;
04:25secondly we get better results, smoother result because we have that wider
04:30fuzziness range to work with.
04:31Now I will go ahead and click OK in order to accept that result.
04:35Press the F key a couple of times in order to fill the screen with the image and
04:38go ahead and zoom on in and that is the final effect with these nice, clean,
04:43sharp tendrils of lightning, coming out of this cloud.
04:47Thanks to the power of the Luminance Exclusion slider bars and the Blend If
04:51option, that gives you channel by channel control, here inside Photoshop.
